>Description:
ufs2 hdd mounted in a directory of ufs hdd, say
/CCC is my ufs hdd, /CCC/DDD is the ufs2 hdd.
/CCC/DDD is owned by nobody:nobody mode 755.
from within /CCC/DDD directory, 'hd ..' works for users nobody and root, yet it doesn't work for other users such as ftp (says 'hd: ..: Permission denied').
This error actually makes tools like 'find' or 'ls -R' to fail.
I have 4 IDE hard disk drives on the system. 3 of them have ufs filesystem, the fourth has ufs2 filesystem.
/dev/ad0s1a /
/dev/ad0s1e /usr
/dev/ad0s1d /var
/dev/ad0s1f /home
/dev/ad0s1g /usr/AAA
/dev/ad1s1e /usr/AAA/BBB/CCC
/dev/ad2s1e /usr/AAA/BBB/CCC/hdd3 <- hd .. works just fine here
/dev/ad3s1e /usr/AAA/BBB/CCC/hdd4 <- this one is ufs2

>How-To-Repeat:
create similar configuration (mount ufs2 hdd from within ufs), set up access rights as described above, run 'hd ..' as some other user from the top of ufs2.
