I understand how permission works and that *most* apps should work
fine. But, are not any (perhaps system or desktop environment),
which depends e.g. "/etc/login.defs" defined "GID_MIN" variable?
Or have some GID boundaries hard-compiled (something as suexec has)?
Or when may be some SELINUX problems here?
