Running FreeBSD 2.0, umount seems to be broken.
The problem in a nutshell:
-------------------------
umount -a -t nfs
umount -a -t ufs
umount -a -t procfs all run without error, but fail
to unmount anything.
The corollary is that the system allows me
to mount already mounted nfs filesystems with
a 'mount -a -t nfs'.
If in this way I mount nfs filesystems, say, three
times in succession, they will each show up as
three separate entries in a "df" listing.
If I then wish, I can remove these entries with
successive umount's.
and
umount -a -t cd9660 barfs with "umount: cd9660: unknown mount type"
even though 'lsvfs' reports:
Filesystem Index Refs Flags
-------------------------------- ----- ----- -----
ufs 1 2 0
nfs 2 2 0
msdos 4 1 0
procfs 12 2 0
cd9660 14 1 0
I wiped my installation, and started with a fresh 0210-snapshot system,
but these problems persist.
Any comments/suggestions are welcome. Please respond via mail to
