If I go to the su prompt and type joe /root /.profile joe says that it's read only.
Yet, from su I type ls -l /root.profile and get:
- -rw-rw-r-- 1 root root 272 Jan 14 2006 .profile
If I try to rename or delete .profile I get : Read-only file system.
And lastly changing /etc/.profile or any other .profile has no effect
