About early gdm logon

There are a number of advantages to starting gdm early.

1) no rhgb means we don't have to start two X servers during the boot
up process.  This means faster bootup, less badness on bad hardware,
etc...

2) The user can potentially login sooner if we only limit login until
the services that the user absolutely needs are started.

3) The system feels like it boots faster if the user sees a login screen
early.

4) The user can type their username and password as soon as a login
screen appears, then walk away--get coffee whatever--and come back with
it all logged in.

Note, even if we say "the services that the user absolutely needs" in 2)
above is "all services that we're going to start", it still has the
other mentioned advantages.

We still need to make some changes in lower-levels of the distro before
dm early-login mode will work.  You can track progress here if you're
