I submitted a request to the GDM documentation folks. Thanks for the pointer.
Rephrasing my question: Let's say I have 50 machine in my cluster, with hostnames "linux01" "linux02" ... "linux50" In previous versions of SL (SL5 and 6 at least), I could modify the login banner to be "%n.university.edu" and then each of the machines would display the appropriate login machine name, "linux01.university.edu" on the linux01 machine (for example). I assume that the %n referred to a shell variable, hostname, but I've never checked. That feature seems to be missing in RHEL7 Nathan On Sat, Aug 29, 2015 at 6:23 PM, greg boyd <[email protected]> wrote: > sorry. i guess that solution was covered in the document you referenced. > (thanks by the way - i had to figure this crap out myself.) maybe i > misunderstood your question... > > > On Sat, Aug 29, 2015 at 4:16 PM, greg boyd <[email protected]> wrote: > >> You need to set a couple of values using dconf.
