root can't view manpages (incl. strace)
For some reason, root cannot view manpages. If I type "man ls" as root,
I get the following:
man: can't create a temporary filename: Permission denied
It works fine as an ordinary user. I did an strace on the command, but
I'm not sure what to make of it. I've included the output below. If
anyone could take a look and give me some suggestions, I would really
appreciate it.
Thanks,
Brian
