                      3: This file is intended to be a brief introduction to the build
                      4: process and a reference on what to do if something doesn't work.
                      5:

                     12:        Statfs(2) and friends have been replaced with statvfs(2). Before
                     13:        installing a newly build userland make sure that you are running
                     14:        a newly built kernel with COMPAT_20 set. In addition your libc
                     15:        build might not work (undefined SYS_statfs symbol) because make
                     16:        clean does not know how to remove files it does not know about
1.116     christos   17:        anymore. Manually remove all generated .S sources and objects
                     18:        from the libc build directory.

                     21:        The method by which athhal-elf.o gets pulled into i386 kernel builds
1.117   ! jmc        22:        has been changed. The file is now stored as a uuencoded file in CVS
1.114     jmc        23:        and the generated Makefile will use the new .uue rules from bsd.file.mk
                     24:        to build it.
                     25:
                     26:        This means you must have the latest bsd.files.mk installed when
                     27:        building a kernel without USETOOLS=yes.

                     30:        A bug in the cgd(4) blowfish code was corrected, without
                     31:        provision of backwards compatibility, after several public
                     32:        notices over several months. Users of cgd with blowfish cipher
                     33:        ONLY must dump their data before updating their kernels, and
                     34:        recreate cgd's and restore data using the new kernel. See
                     35:        (recent message to current-users, URL when mail-index has updated)

                     38:        On acorn32, the opms and qms drivers have been withdrawn, and
                     39:        the old wsqms driver is now called qms.  Kernel config files
                     40:        will need updating.  See the ones in sys/arch/acorn32/conf
                     41:        for examples.

                     45:        needed, and will need to be deleted from kernel configuration

                     50:        added, and the restrictive fsck checks have been reenabled
                     51:        when using those layouts.  If you have been using -current
                     52:        since 20030402, you may find that fsck again signals fatal
1.110     dbj        53:        superblock mismatches.  To repair, make sure you have
1.111     simonb     54:        an updated fsck_ffs and then you can use fsck_ffs -b 16 -c 4
1.109     dbj        55:        to complete the filesystem upgrade.  A message has
1.111     simonb     56:        been added to the kernel which should detect this problem.

1.99      mrg        62:        It's necessary to "make cleandir" to ensure that

                     76:        of our newly expanded ffs fs_flags.  This should only
                     77:        affect users who installed or upgraded in September of 2003.
1.109     dbj        78:        A small utility program was posted to tech-kern which
1.111     simonb     79:        should fix this problem, and a warning message was added
                     80:        to the kernel which should discover and warn about it.  See

                     85:        code has been deprecated to COMPAT_16. Make sure that your running
                     86:        kernel has COMPAT_16 enabled before building userland.

1.89      christos  106:
                    107: 20030516:
                    108:        Due to bugs in the export handling code, invalid export lines
                    109:        were accepted before and caused the kernel to panic when
                    110:        mountd got restarted because it freed memory that had already
                    111:        been freed. This has been fixed and the kernel checks
                    112:        export addresses very strictly. If you upgrade your kernel,
                    113:        make sure you also upgrade mountd, because if your export
                    114:        file contains lines with an old inet4 address syntax (i.e.
                    115:        a.b.c or a.b or a), they will get rejected by the new kernel.
1.87      bjh21     116:

                    118:        The superblock layout for FFS was changed.  If you have 1.6
                    119:        fsck binaries, they will signal a fatal superblock mismatch
                    120:        with the first alternate, because they compare too many
                    121:        fields (even ones that aren't useful).  If possible, upgrade
                    122:        your fsck_ffs binary before using a new kernel.
                    123:        None of this signals actual filesystem damage.
