Generally there were three types of answers:
1. You don't have access to /.
2. You have an NFS permission problem.
3. You don't have access to an underlying mount point.
The answer is 3. /u01 was mounted on a dir where I didn't have
access. The mount hid this fact. Unmounting u01, chmoding 0755 /u01,
and remounting /u01 solved the problem. I anticipate having more
problems like this: being the paranoid type, I made root's umask 027
about 3 weeks ago. I'll just consult my trusty log book to see what I
have done the last three weeks...
I think from the information given one can deduce that 1 is not true
(viz., the permissions on / are at least ------r-x). Admittedly I
wasn't as verbose as I should have been.
Answer 2, though possibly correct, is not correct because all
filesystems are local (I should have mentioned this).
I am very impressed how quickly I received responses and how polite
they were.
