                      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.

        !            14:        has been changed. The file is now stored as a uuencode file in CVS
        !            15:        and the generated Makefile will use the new .uue rules from bsd.file.mk
        !            16:        to build it.
        !            17:

                     23:        provision of backwards compatibility, after several public
                     24:        notices over several months. Users of cgd with blowfish cipher
                     25:        ONLY must dump their data before updating their kernels, and
                     26:        recreate cgd's and restore data using the new kernel. See

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

                     42:        added, and the restrictive fsck checks have been reenabled
                     43:        when using those layouts.  If you have been using -current
                     44:        since 20030402, you may find that fsck again signals fatal
1.110     dbj        45:        superblock mismatches.  To repair, make sure you have
1.111     simonb     46:        an updated fsck_ffs and then you can use fsck_ffs -b 16 -c 4
1.109     dbj        47:        to complete the filesystem upgrade.  A message has
1.111     simonb     48:        been added to the kernel which should detect this problem.

1.111     simonb     71:        should fix this problem, and a warning message was added
                     72:        to the kernel which should discover and warn about it.  See

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

                    100:        Due to bugs in the export handling code, invalid export lines
                    101:        were accepted before and caused the kernel to panic when
                    102:        mountd got restarted because it freed memory that had already
                    103:        been freed. This has been fixed and the kernel checks
                    104:        export addresses very strictly. If you upgrade your kernel,
                    105:        make sure you also upgrade mountd, because if your export
                    106:        file contains lines with an old inet4 address syntax (i.e.
                    107:        a.b.c or a.b or a), they will get rejected by the new kernel.

                    111:        fsck binaries, they will signal a fatal superblock mismatch
                    112:        with the first alternate, because they compare too many
                    113:        fields (even ones that aren't useful).  If possible, upgrade
                    114:        your fsck_ffs binary before using a new kernel.
                    115:        None of this signals actual filesystem damage.
