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

                     32:        added, and the restrictive fsck checks have been reenabled
                     33:        when using those layouts.  If you have been using -current
                     34:        since 20030402, you may find that fsck again signals fatal
1.110     dbj        35:        superblock mismatches.  To repair, make sure you have
1.111     simonb     36:        an updated fsck_ffs and then you can use fsck_ffs -b 16 -c 4
1.109     dbj        37:        to complete the filesystem upgrade.  A message has
1.111     simonb     38:        been added to the kernel which should detect this problem.

                     67:        code has been deprecated to COMPAT_16. Make sure that your running

                     92:        mountd got restarted because it freed memory that had already

                     94:        export addresses very strictly. If you upgrade your kernel,
                     95:        make sure you also upgrade mountd, because if your export

                     97:        a.b.c or a.b or a), they will get rejected by the new kernel.

                    101:        fsck binaries, they will signal a fatal superblock mismatch
                    102:        with the first alternate, because they compare too many
                    103:        fields (even ones that aren't useful).  If possible, upgrade
                    104:        your fsck_ffs binary before using a new kernel.
