Operating Systems Linux Red Hat restrict access of a user to two directories only Post 302185541 by jim mcnamara on Tuesday 15th of April 2008 08:33:50 AM

For the user test to be able to run some utilities he may need read access to some files perhaps in /etc or /lib.

Your best bet is to chroot this user - put the user in chroot jail, creates links in his home directory to /tmp1 & /tmp2. This is what is often done with ftp accounts to lock them into completely known file trees
