Adding /sbin/mount_kernfs (and /kern dir) and removing /bin/sysctl
make instbin fit sysinst.fs 1440KB.

"sed -n -e 's/\(^[ws]d[0-9]\) at.*/\1/p' /kern/msgbuf"
seems to work (on i386), but it still has a problem:
MSGBUFSIZE is 32KB on atari, then msgbuf could include messages from
the previous kernel so the same disk could appear multiple times.
(uniq by sed?)
