In older versions of SL one could include the machine name in the login
banner.  Somethings like "%n.university.edu" in the login banner config
screen would produce "physics1.university.edu" at the login screen.

In the present RHEL7 documentation (link below) I don't see this option in
the dconf docs.  Is there an easy way to include machine name in the gdm
login screen?
