Brief description of the issue:
After restoring the system, the bin commands, e.g. ping, ls, cp and so on, are getting "permission denied" with regular user( e.g. user named silentmobius that is listed at /etc/passwd)
Work-around, if any:
I am changin the permissions with root and setting the id with setuid.

I am not a Red Hat / Fedora or CentOS user but
I think this issue is basically the same or at least similar as
#1175
therein see in particular
#1175 (comment)
and
#1411

In genaral when you need to do some special adaptions after "rear recover"
you can automate that via POST_RECOVERY_SCRIPT,
see usr/share/rear/conf/default.conf

@silent-mobius could you list the exact permissions after the recovery? Never encountered this problem description before.

After some research, we found that it's tar issue. When backup.tar.gz is created it's changing the permissions of bin files to 600.
