   Yupp. Hmm... Just after I had installed, I got a warning about /
(this happened after the init.root switch had occured). I assumed it was
due to a missing / entry in /etc/fstab. I added an entry for / in fstab,
and the message disappeared. I'll remove that entry it and see what the
message is.

   From my "jan" user (ls never fails with this user):

$ stat /
5120 2 drwxr-xr-x 21 root wheel 1488 1024 "Sep 19 19:51:19 2007" "Sep 19
19:13:48 2007" "Sep 19 19:14:32 2007" "Jan  1 01:00:00 1970" 16384 4 0 /


   From my "pkgsrc" user:

$ whoami
pkgsrc
$ pwd
/home/pkgsrc
$ ls -l
ls: .: Permission denied
$ stat /
5120 2 drwxr-xr-x 21 root wheel 1488 1024 "Sep 19 19:51:19 2007" "Sep 19
19:13:48 2007" "Sep 19 19:14:32 2007" "Jan  1 01:00:00 1970" 16384 4 0 /

   Hmm.. It returns the same information while problem is "active".
