After having tried various things, and timed them,
we tend to be a lot less confident that a simple solution
could be implemented easily.

The vast majority of startup time seems to be reading stuff
of the disk; parallelizing init scripts doesn't
help with that. Starting up GDM earlier may work, but
with the downsides that:

 - You have to figure out what services are safe to
   start after login.
 - You may have a unresponsive system during login.

is a recently created tracker bug for this issue.
