It returns long output like (the random string here is made up by me):
34209381afaa07fa9dfsaf at schoolserver.lccnjimeta.org/Telepathy

and the number of "users has grown some this morning, from about 4 to over
10

(we have a number of XO's in use here this morning for continued teacher
training)

So I definitely buy that some automagic is going on here.  Is there perhaps
documentation I can view that explains to me how to create different groups
for different classes and generally manage things without the now obsolete
web interface?
(real world example: I would like to put all of my 5th graders in a group
together, my 2nd graders in another, etc)  I might even want to change these
on a regular basis.

Is this all done through moodle perhaps?  Is there documentation I should be
using for that?  If you could send me a link it would be much appreciated.

Dan: service pgsql-xs supports chkconfig, but is not reerenced in any
runlevel (run 'chkconfig --add pgsql-xs')

Should I run this as it says?

Other oddities noticed during reboot if they help..:

klogctl during boot returns 'invalid argument'
mshbonds and wmeshs do not seem to be present
could not connect to server postgres as well.
