12: The end-user modifiable X11 configuration has been moved
13: from /usr/X11R6/lib/X11/<dir> to /etc/X11/<dir>.
14: Ensure that src and xsrc is up to date, and run
15: "make cleandir" in src/x11 before your next build.

1.119 atatat 17: 20040426:
18: Support for the original dynamic sysctl node structure has
19: been removed in favor of the newer layout. This affects
20: consumers of the create and delete interface, as well as
21: the dynamic discovery mechanism. This is believed only to
22: be the sysctl(8) binary itself, at this point in time, so
23: the only effect of this should be that a sysctl binary
24: built from sources dated between 2003/12/04 and 2004/03/24
25: will not work on a kernel built from sources dated after
26: 2004/04/25. If you need a new sysctl binary but build.sh
27: does not work, make sure that your revision of
1.120 atatat 28: src/sys/sys/sysctl.h is 1.112 (or later), and then the
29: do the following:
1.119 atatat 30:
1.120 atatat 31: cd /usr/src (or wherever your source tree is)
32: make USETOOLS=no includes
33: cd lib/libc
34: make USETOOLS=no dependall install
35: cd ../../sbin/sysctl
1.119 atatat 36: make USETOOLS=no dependall install
37:
1.122 ! itojun 38: If you are using older sysctl binary, GNU autoconf would fail to
! 39: identify your machine architecture, and tries to build binary for
! 40: "unknown-unknown-netbsd20F" or something like that. if that happens,
! 41: make sure to follow the above steps.
! 42:
1.118 dbj 43: 20040425:
44: The ffs superblock issues listed below under 20040109 and 20030402
45: are now automatically addressed by the /etc/rc.d/fixsb script or by
46: sysinst when it checks a a filesystem. The manual fsck_ffs -b16 -c4
47: invocation mentioned below will continue to work and is now
48: automated by those scripts. Note that under certain circumstances,
49: affected filesystems upgraded to a -current kernel first before
50: upgrading their userland with the fixsb and fsck_ffs fixes may
51: encounter a 'freeing free inode' panic when writing to the affected
52: filesystem, so it is a good idea to repair the filesystem as soon as
53: possible. For more details on the fixsb script, see pr install/25138.
54:
1.115 christos 55: 20040418:
1.121 lukem 56: statfs(2) and friends have been replaced with statvfs(2). Before
1.115 christos 57: installing a newly build userland make sure that you are running
58: a newly built kernel with COMPAT_20 set. In addition your libc
59: build might not work (undefined SYS_statfs symbol) because make
60: clean does not know how to remove files it does not know about
1.116 christos 61: anymore. Manually remove all generated .S sources and objects
62: from the libc build directory.
1.115 christos 63:
1.114 jmc 64: 20040326:
65: The method by which athhal-elf.o gets pulled into i386 kernel builds
1.117 jmc 66: has been changed. The file is now stored as a uuencoded file in CVS
1.114 jmc 67: and the generated Makefile will use the new .uue rules from bsd.file.mk
68: to build it.
69:
70: This means you must have the latest bsd.files.mk installed when
71: building a kernel without USETOOLS=yes.
72:
1.113 dan 73: 20040318:
74: A bug in the cgd(4) blowfish code was corrected, without
75: provision of backwards compatibility, after several public
76: notices over several months. Users of cgd with blowfish cipher
77: ONLY must dump their data before updating their kernels, and
78: recreate cgd's and restore data using the new kernel. See
79: (recent message to current-users, URL when mail-index has updated)
80:
1.108 bjh21 81: 20040313:
82: On acorn32, the opms and qms drivers have been withdrawn, and
83: the old wsqms driver is now called qms. Kernel config files
84: will need updating. See the ones in sys/arch/acorn32/conf
85: for examples.
86:
1.106 bjh21 87: 20040125:
88: On acorn32, the beep and sysbeep devices are no longer
89: needed, and will need to be deleted from kernel configuration
90: files.
1.105 bjh21 91:
1.102 dbj 92: 20040109:
93: Compatibility for old ffs superblock layouts has been
94: added, and the restrictive fsck checks have been reenabled
95: when using those layouts. If you have been using -current
96: since 20030402, you may find that fsck again signals fatal
1.110 dbj 97: superblock mismatches. To repair, make sure you have
1.111 simonb 98: an updated fsck_ffs and then you can use fsck_ffs -b 16 -c 4
1.109 dbj 99: to complete the filesystem upgrade. A message has
1.111 simonb 100: been added to the kernel which should detect this problem.
101: See the following discussion for more information:
1.112 keihan 102: http://mail-index.NetBSD.org/current-users/2004/01/11/0022.html
1.102 dbj 103:
1.99 mrg 104: 20031203:
1.100 keihan 105: New binutils builds may fail due to old dependencies.
1.99 mrg 106: It's necessary to "make cleandir" to ensure that
107: the dependencies will be rebuilt correctly.
1.98 wiz 108:
109: 20031111:
110: A newer mkdep is needed. Error noting that is
111: cc: Ambiguous abbreviation --
1.97 lukem 112:
113: 20031008:
114: /usr/include/sys/disklabel_mbr.h was removed.
115: It's necessary to "make cleandir" to ensure that
116: the dependencies will be rebuilt correctly.
1.96 christos 117:
1.109 dbj 118: 20031007:
1.111 simonb 119: A sign exension bug was fixed which set all the high bits
120: of our newly expanded ffs fs_flags. This should only
121: affect users who installed or upgraded in September of 2003.
1.109 dbj 122: A small utility program was posted to tech-kern which
1.111 simonb 123: should fix this problem, and a warning message was added
124: to the kernel which should discover and warn about it. See
125: http://mail-index.NetBSD.org/tech-kern/2003/10/07/0005.html
1.109 dbj 126:
1.96 christos 127: 20030906:
128: With the addition of siginfo support the old signal trampoline
129: code has been deprecated to COMPAT_16. Make sure that your running
130: kernel has COMPAT_16 enabled before building userland.
1.94 christos 131:
132: 20030801:
1.95 wiz 133: With the new openssl, there is some header and library shuffling.
1.94 christos 134: rm -f /usr/include/des.h /usr/include/kerberosIV/* /lib/libdes* \
1.95 wiz 135: /usr/lib/libdes* before building.
1.92 wiz 136:
137: 20030703:
138: Texinfo was updated to 4.6. To avoid failures when trying to
139: build the included texinfo files, do:
140:
141: cd src/gnu/usr.bin/texinfo
142: make MKINFO=no dependall install
1.90 wiz 143:
144: 20030630:
1.101 junyoung 145: Groff was updated to 1.19; it's probably necessary to do
1.91 wiz 146: cd share/mk && make install
1.90 wiz 147: cd src/gnu/usr.bin/groff
148: make MKMAN=no dependall install
149: (untested).
1.89 christos 150:
151: 20030516:
152: Due to bugs in the export handling code, invalid export lines
153: were accepted before and caused the kernel to panic when
154: mountd got restarted because it freed memory that had already
155: been freed. This has been fixed and the kernel checks
156: export addresses very strictly. If you upgrade your kernel,
157: make sure you also upgrade mountd, because if your export
158: file contains lines with an old inet4 address syntax (i.e.
159: a.b.c or a.b or a), they will get rejected by the new kernel.
1.87 bjh21 160:
161: 20030402:
162: The superblock layout for FFS was changed. If you have 1.6
163: fsck binaries, they will signal a fatal superblock mismatch
164: with the first alternate, because they compare too many
165: fields (even ones that aren't useful). If possible, upgrade
166: your fsck_ffs binary before using a new kernel.
167: None of this signals actual filesystem damage.
1.85 atatat 168:
169: 20030324:
170: sendmail version 8.12.8 was imported. Since sendmail is
171: now setgid to the smmsp group, and runs in "collection"
172: mode for most common activities, there is a new config
173: file called submit.cf that needs to live in /etc/mail.
174: The generic submit.cf sample in /usr/share/sendmail/cf
175: is named netbsd-msp.cf. Upgrading your regular sendmail
176: configuration file is also strongly advised.
177:
178: See the section named "MESSAGE SUBMISSION PROGRAM" in
179: the updated /usr/share/sendmail/README file for more
180: information.
1.82 wiz 181:
182: 20030117:
183: Texinfo was updated to 4.3. To avoid failures when trying to
184: build the included texinfo files, do:
185:
186: cd src/gnu/usr.bin/texinfo
187: make MKINFO=no dependall install
1.81 lukem 188:
189: 20021223:
190: The METALOG format changed slightly, to remove the leading
191: "${DESTDIR}" from path names.
192: This only affects people building with UNPRIVED.
193: For complete safety, remove the DESTDIR entirely and
194: update tools/mtree, before running make build.
1.88 itojun 195:
196: 20021219:
197: CVS repository layout was changed. See the following for details
198: if you are using (anonymous) cvs to update your tree.
199:
1.93 salo 200: http://mail-index.NetBSD.org/netbsd-announce/2002/12/19/0000.html
1.80 lukem 201:
202: 20021219:
203: install(1) had a '-N dbdir' option added, to specify an
204: alternate location to look up users & groups (instead
205: of the host system passwd(5) and group(5) databases).
206:
207: The build system was modified to take advantage of
208: this option (using ${NETBSDSRCDIR}/etc), so if you
1.83 kei 209: use USETOOLS==no, you may have to rebuild and
1.80 lukem 210: reinstall usr.bin/xinstall first.
1.78 lukem 211:
212: 20021130:
213: fparseln(3) moved from libutil to libc.
214: If building to DESTDIR=/, reinstall the includes
215: and rebuild libc:
216: make includes
217: make do-lib-libc
218: If using build.sh, "cd tools/compat && make clean"
219: before rebuilding the tools.
1.77 lukem 220:
221: 20021126:
222: The mk.conf(5) variable SYS_INCLUDE has been deprecated,
223: including the optional "SYS_INCLUDE=symlinks" support.
224: All header files, including <sys/*.h> are copied into
225: /usr/include.
1.76 thorpej 226:
227: 20021121:
228: The C run-time support files crtbegin.o and crtend.o
229: (and their companions crtbeginS.o and crtendS.o) were
230: split up, with new crti.o and crtn.o files resulting.
231: This means that libtool needs to be rebuilt once the
232: new libraries are installed. The process of rebuilding
233: libtool will cause it to automatically notice the new
234: required files, but it *must* be rebuilt in order to
235: do this.
236:
237: An out-of-date libtool will result in shared libraries
238: which lack _init() and _fini() routines, which means that
239: their global contructors/destructors will not be invoked.
1.75 thorpej 240:
241: 20021121:
242: A bug related to how ARM ELF objects were tagged has been
243: corrected.
244:
245: NetBSD ARM ELF uses the soft-VFP floating point model by
246: default. However, the assembler lacked support for marking
247: objects as using the VFP floating point format, and the
1.79 wiz 248: compiler was not properly passing the flag indicating "soft-VFP"
1.75 thorpej 249: to the assembler.
250:
251: Unfortunately, this means that the linker will now consider
252: old (i.e. not marked "softvfp") NetBSD ARM ELF objects to be
253: incompatible with new (properly marked) objects.
254:
255: The problem will only manifest itself if you attempt to compile
256: a new program using the fixed toolchain, and link that program
257: against old libraries which do not have the proper "softvfp"
258: markings. ALL OF YOUR EXISTING BINARIES AND SHARED LIBRARIES
259: WILL CONTINUE TO WORK PROPERLY.
260:
261: The only work-around for the problem is to recompile all of
262: the libraries on the system. The easiest way to do this for
1.79 wiz 263: system libraries is to install a binary snapshot; they are
1.93 salo 264: generally available on releng.NetBSD.org. Any packages you
1.75 thorpej 265: have installed which supply libraries will have to be recompiled
266: if you wish to link new programs against those libraries.
267:
268: If you have questions about this matter, please contact
1.93 salo 269: port-arm@NetBSD.org.
1.73 provos 270:
271: 20021011:
272: Systrace has been improved to support privilege elevation.
273: Updating the kernel requires the userland part of systrace
1.79 wiz 274: to be rebuilt.
1.72 thorpej 275:
276: 20021010:
277: The config(8) grammar was changed to allow options to register
278: dependencies on attributes, as well as other options. Users
279: must update and reinstall usr.sbin/config before building a new
280: kernel.
1.70 thorpej 281:
282: 20021009:
283: A new attribute dependency syntax was introduced to config(8),
284: which is now used by the SCSI configuration description. Users
1.71 wiz 285: must update and reinstall usr.sbin/config before building a new
1.70 thorpej 286: kernel.
1.69 thorpej 287:
288: 20021003:
289: Several changes have been made to the autoconfiguration
290: framework. Users must update and reinstall usr.sbin/config
291: before building a new kernel.
1.74 jschauma 292:
293: 20021001:
294: The i386mp branch has been merged. To compile a kernel, users
295: will need to add the option 'cpu* at mainbus?' to their configuration
296: file. Multiprocessor kernels will need
297: ioapic* at mainbus? apid ?
298: options MULTIPROCESSOR
299: options COM_MPLOCK
1.68 lukem 300:
301: 20020922:
302: MKDYNAMICROOT=yes enabled by default, which means that
303: certain shared libraries are installed into /lib, the shared
304: linker is installed into /libexec, and all programs in /bin
305: and /sbin are dynamically linked.
306: If you do not use "make build", you should ensure that
307: you have the libraries and shared linker in the new locations,
308: with:
309: make do-lib-csu do-lib-libc do-lib do-gnu-lib do-ld.elf_so
1.67 lukem 310:
311: 20020917:
312: USE_NEW_TOOLCHAIN has been replaced with:
313: - TOOLCHAIN_MISSING -- set to "yes" on platforms for which
314: there is no working in-tree toolchain (hppa, ns32k, sh5,
315: x86_64).
316: - EXTERNAL_TOOLCHAIN -- if defined by the user, points to the
1.79 wiz 317: root of an external toolchain (e.g. /usr/local/gnu). This
1.67 lukem 318: enables the cross-build framework even for TOOLCHAIN_MISSING
319: platforms.
1.66 gehenna 320:
321: 20020906:
322: gehenna-devsw has been merged into the trunk. Need to update and
1.79 wiz 323: reinstall usr.sbin/config before building the kernel.
1.65 lukem 324:
325: 20020822:
326: Crunched rescue tools (contents of /bin and /sbin, plus others)
327: are now provided in /rescue.
328:
329: To ensure that these are built statically linked (no matter
330: what the setting of LDSTATIC is), use a crunchgen(1) built
331: from sources newer than 20020820 (see the next entry).
332:
333: 20020820:
334: crunchgen(1) changed to ensure that the generated program
335: is statically linked.
336:
337: Solution: update and reinstall usr.bin/crunch
1.84 grant 338:

363: the build process).
1.60 sommerfe 364:
365: 20020426:
366: NBUILDJOBS obsoleted in favor of just using -j.
1.59 lukem 367:
368: 20020426:
369: etc/postinstall added, which performs various checks for
370: configuration file updates and changes, and can fix most of
371: the problems identified.
372: This should make it much easier to upgrade a system's
373: configuration from earlier systems (as far back as NetBSD 1.5).

381: on send(2) operation. Be sure to have sbin/rtsol and usr.sbin/rtsold
1.55 itojun 382: newer than November 2001 when you upgrade the kernel.
383:
1.54 itojun 384: 20020311:
385: ssh configuration files were moved from /etc to /etc/ssh. Beware
386: if you restart your machine from remote. Note that sshd.conf needs
387: to be changed (due to the use of "/etc" inside).
388:

407: If you're attempting to build a snapshot on sparc64 and are getting
408: reloc errors from the toolchain groff binary this means your native
409: toolchain has some broken C++ bits.
410:
411: To fix:
412:
413: Build a new toolchain (i.e. build.sh -t)
414: Use the new toolchain to build and install natively (i.e. /usr/lib)
415:
416: gnu/lib/libgcc
1.51 pooka 417: gnu/lib/libstdc++
1.49 jmc 418:
419: After this a snapshot will be able to be built.
420:
1.47 jmc 421: 20011201:
422: In order for a sparc64 build to work you must have a working awk. If
423: you've built and installed a system with the new toolchain up to this
1.52 wiz 424: point you do not have a working awk as its ability to do floating
1.47 jmc 425: point is broken.
426:
427: To build:
428:
429: remake and install gnu/lib/libgcc
430: remake and install gnu/usr.bin/gawk into /usr/bin (make sure it links
1.48 jmc 431: against the new libgcc.a)

446: see pre-generated .txt and .html versions) describes the build
447: procedure in great detail. BUILDING, and the USE_NEW_TOOLCHAIN
448: build process, are intended in the long run to replace this
449: manual update log.
450:
451: Users building a USE_NEW_TOOLCHAIN system should read the
452: BUILDING document for caveats. Generally, BUILDING supersedes
453: UPDATING for these systems, as tool updating is taken care of
454: by the new build system.
1.42 perry 455:
456: 20011028:
457: src/etc/Makefile now needs install to be able to handle
458: symlinks that point to nowhere. A bug in install that
459: prevented this was corrected.
460:
461: Solution: update and reinstall usr.bin/xinstall
462: Better Solution: Use the new toolchain and it will just work
463: for you.
1.40 lukem 464:
465: 20011006:
466: /etc/mtree/NetBSD.dist has been updated to take advantage of
467: absolute path support added to mtree(8). Older mtree(8)s don't
468: understand the format.
469:
470: Solution: update and reinstall usr.sbin/mtree
1.39 jmc 471:

473: Crunchgen has been updated to work via reach-over makefiles. Updating
474: is suggested before running a snapshot build
1.36 tv 475:
1.35 thorpej 476: 20010915:
477: The new "ubcperf" code committed by Chuck Silvers removed
478: a header file, uvm/uvm_vnode.h. There may be stale .depend
479: files that still reference this file.
480:
481: Solution: "make cleandir && make dependall" in affected
482: directories.
1.31 enami 483:
484: 20010803:
485: grep.info is now built from grep.texi using makeinfo. Since it
486: requires makeinfo v4.0, you need to install new texinfo before
487: building gnu/usr.bin/grep. To install new texinfo, please follow
488: the instruction described in 20010726 entry.
1.30 enami 489:
1.64 sommerfe 490: 20010803:
1.41 wiz 491: (i386 only): i386 kernel now uses new instructions like
1.111 simonb 492: `fxsave' which old gas doesn't understand. To build the
1.64 sommerfe 493: kernel successfully, you need to build and install a new toolchain,
494: (i.e., build.sh -t) or (temporarily) comment out "options I686_CPU"
495: from your kernel configuration until you rebuild your userland.
496: See 20011029 above and BUILDING file in this directory for more information.
497: [updated 20020630 since i386 gas moved when USE_NEW_TOOLCHAIN enabled]
1.29 bjh21 498:

500: Bootloader update on ELF platforms. DDB in kernels from before
501: this will be unable to read symbol tables provided by newer
502: bootloaders.
1.27 assar 503:
504: 20010726:
505: Texinfo was updated to 4.0. To avoid failures when trying to
1.28 assar 506: build the included texinfo files, do:
507:
508: cd src/gnu/usr.bin/texinfo
509: make MKINFO=no dependall install
1.25 thorpej 510:
511: 20010718:
512: Enabled correct .init/.fini processing in crt0. The way this
513: was done was to change a -I directive to cc(1), which means
514: make(1) will have a stale dependency (it will be checking the
515: timestamp on the wrong "dot_init.h").
516:
517: The symptom you will see is that new programs die with SIGSEGV
518: if you have a stale dependency.
519:
520: Solution: "make cleandir" in both lib/csu and libexec/ld.elf_so
521: before starting your build.
1.26 thorpej 522:
523: 20010628:
524: A construct was added to uvm_page.h that uncovered a bug
525: in lint(1). If you get a warning/error about a non-portable
526: bitfield, update your lint(1) before proceeding.
1.21 jmc 527:
528: 20010226:
1.22 jmc 529: Added named user/group to system. Need to hand add this in or builds
1.21 jmc 530: will break as mtree aborts early.
531:
532: To work around add by hand:
533:
534: named:*:14:
535:
1.22 jmc 536: to /etc/group and add:
537:
538: named:*:14:14::0:0:Named pseudo-user:/var/named:/sbin/nologin
539:
540: to master.passwd (use vipw for instance if doing by hand).
541:
542: Now a make build should progress.
1.18 jmc 543:
544: 20010219:
1.52 wiz 545: get/setprogname() added. Any hostprogs that may use this will need
1.111 simonb 546: to be bootstrapped manually until the host system is current.
1.18 jmc 547:
1.111 simonb 548: Known problems: sys/arch/macppc/stand/fixcoff
1.19 cgd 549: usr.sbin/config (adding -DMAKE_BOOTSTRAP to
550: CFLAGS and rebuilding should work)
1.20 jmc 551: usr.sbin/mdsetimage - Build a static copy if
1.111 simonb 552: building a snapshot before fully bootstrapped.
1.15 christos 553:
554: 20010204:
555: prepare the code to compile with stricter gcc flags. in
556: particular start eliminating redundant declarations. Yacc
557: needs to be installed before make build.
1.10 christos 558:
559: 20010114:
560: introduce .if commands(target) in make(1). You need to
561: bring everything up-to-date first, then without installing
1.23 tron 562: anything make and install in usr.bin/make, then proceed
1.10 christos 563: with make build.
1.9 sommerfe 564:
565: 20010101:
566: bsd.subdir.mk committed 20001230 had a bug which caused
567: afterinstall targets to run too soon; update again.
1.8 sommerfe 568:
569: 20001230:
570: New share/mk files needed to support .WAIT in SUBDIR variables.
571: If you get make errors,
572: (cd share/mk; make install)
573: Also, PRINTOBJDIR has changed and is now used more heavily.
1.6 ad 574:
575: 20001019:
1.7 ad 576: The `ca' device driver has been replaced by `ld'; although the
1.6 ad 577: major and minor numbers haven't changed, you should update your /dev
578: directory.
1.1 abs 579:
1.4 itojun 580: 20000929:
581: The following make directives are obsoleted.
582: MKCRYPTO_RSA NOCRYPTO_RSA NOCRYPTO_RC5 NOCRYPTO_IDEA
583: By default, RSA is built into libcrypto. IDEA and RC5 will not be
1.16 wiz 584: built into libcrypto. By using MKCRYPTO_{RC5,IDEA}, you can build
1.4 itojun 585: additional library libcrypto_{idea,rc5}.
1.1 abs 586:
587:
588: Hints for a more successful build:
589: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.2 mrg 590: Build a new kernel first:
591: This makes sure that any new system calls or features
592: expected by the new userland will be present. This
593: helps to avoid critical errors when upgrading.
1.1 abs 594: Use object directories:
595: This helps to keep stale object
596: files from polluting the build if a Makefile "forgets"
597: about one. It also makes it easier to clean up after
598: a build. It's also necessary if you want to use the
599: same source tree for multiple machines.
600: To use object directories:
601: a) cd /usr/src ; make cleandir
1.2 mrg 602: b) Add "OBJMACHINE=yes" to /etc/mk.conf
603: c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1 abs 604: d) cd /usr/src ; make build
1.2 mrg 605: Note that running "make obj" in a directory will create
606: in obj.$MACHINE directory.
1.1 abs 607: Build to a DESTDIR:
608: This helps to keep old
609: installed files (especially libraries) from interfering
610: with the new build.
611: To build to a DESTDIR, set the DESTDIR environment
1.2 mrg 612: variable before running make build. It should be set to
613: the pathname of an initially empty directory.
1.1 abs 614: Problems: you might need to update critical utilities
615: without using DESTDIR since nothing is executed
616: from what is installed in DESTDIR.
617: (See critical utils, below)
618: Build often:
619: This keeps critical utilities current enough to not choke
620: on any other part of the source tree that depends on up to
621: date functionality.
622:
623: What to do if things don't work:
624: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
625: When things don't work there is usually a few things that commonly
626: should be done.
627: 1) make includes
628: This should be done automatically by make build.
629: 2) cd share/mk && make install
630: Again, automatically done by make build.
631:
632: Failsafe rebuild of a small part of the tree:
633: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
634: To make sure you rebuild something correctly you want to do
635: something like the following:
636: 1) Make sure the includes and .mk files are up to date.
637: 2) Make sure any program used to build the particular
638: utility is up to date. (yacc, lex, etc...)
639: 3) cd ...path/to/util...
640: make cleandir
641: rm ...all obj directories...
642: make cleandir # yes, again
643: make obj
644: make depend && make
645:
646: Failsafe rebuild of the entire tree:
647: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
648: If you really want to make sure the source tree is clean and
1.2 mrg 649: ready for a build try the following. Note that sourcing /etc/mk.conf
650: (a make(1) Makefile) in this manner is not right, and will not work
651: for anyone who uses any make(1) features in /etc/mk.conf.
