                      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.

        !            13:        from /usr/X11R6/lib/X11/<dir> to /etc/X11/<dir>.

                     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:

                     39:        The ffs superblock issues listed below under 20040109 and 20030402
                     40:        are now automatically addressed by the /etc/rc.d/fixsb script or by
                     41:        sysinst when it checks a a filesystem. The manual fsck_ffs -b16 -c4
                     42:        invocation mentioned below will continue to work and is now
                     43:        automated by those scripts.  Note that under certain circumstances,
                     44:        affected filesystems upgraded to a -current kernel first before
                     45:        upgrading their userland with the fixsb and fsck_ffs fixes may
                     46:        encounter a 'freeing free inode' panic when writing to the affected
                     47:        filesystem, so it is a good idea to repair the filesystem as soon as
                     48:        possible.  For more details on the fixsb script, see pr install/25138.

1.115     christos   52:        installing a newly build userland make sure that you are running
                     53:        a newly built kernel with COMPAT_20 set. In addition your libc
                     54:        build might not work (undefined SYS_statfs symbol) because make
                     55:        clean does not know how to remove files it does not know about
1.116     christos   56:        anymore. Manually remove all generated .S sources and objects

1.117     jmc        61:        has been changed. The file is now stored as a uuencoded file in CVS
1.114     jmc        62:        and the generated Makefile will use the new .uue rules from bsd.file.mk

                     71:        notices over several months. Users of cgd with blowfish cipher
                     72:        ONLY must dump their data before updating their kernels, and

                     78:        the old wsqms driver is now called qms.  Kernel config files
                     79:        will need updating.  See the ones in sys/arch/acorn32/conf

                     90:        when using those layouts.  If you have been using -current

1.110     dbj        92:        superblock mismatches.  To repair, make sure you have
1.111     simonb     93:        an updated fsck_ffs and then you can use fsck_ffs -b 16 -c 4
1.109     dbj        94:        to complete the filesystem upgrade.  A message has
1.111     simonb     95:        been added to the kernel which should detect this problem.
