complains about "Malformed numbers" while unpacking the dists and
what winds up on the disk isn't correct. Use this as an opportunity
to switch over to bsdcpio since at this point we don't even build
and install the gnu cpio by default. Note sysinstall needed to be
tweaked a bit (dropping tape block size setting) because it seems
bsdcpio doesn't do anything with block sizes, at least as far as
reading from archives goes. That wasn't really a problem since
installations from tape have been broken for a while and the rest
of sysinstall's tape support code will be removed shortly.
can't find fsck_4.2bsd because there was no fstab file saying what
filesystem type it is looking at so it got the filesystem type from
the disk's label. When that fails admins who haven't been in this
situation before are most likely to try "fsck -t ufs /dev/ad0s1a" because
ufs is the type used in fstab files on working systems but that also fails
complaining it can't find fsck_ufs.
This just sets it up so /stand in the MFS image (/sbin is a symlink
to /stand) includes hard links pointing fsck_4.2bsd and fsck_ufs to
fsck_ffs which is what is present in /sbin on installed systems.
