Well:
$ find / /tmp /var /usr -mount -user nobody | xargs ls -l
srwxrwxrwx 1 nobody nogroup 0 Nov 19 04:02
/tmp/.font-unix/fs7100
-rw-rw---- 1 nobody mail 12487 Jun 2 2000
/var/spool/mail/nobody
/tmp/.font-unix:
total 0
srwxrwxrwx 1 nobody nogroup 0 Nov 19 04:02 fs7100
srwxr-xr-x 1 root root 0 Nov 19 04:02 fs7101
I'm not sure that nobody should own *no* files. But files owned by
nobody *should* be minimized. Note that nobody is just another
nonpriviledged user, and that file access isn't of and by itself a
problem.
In some cases, daemons run as 'nobody' (apache under RH, I believe), and
it may be necessary to create temporary files as 'nobody'.
Other thoughts?
