quick boot

[Curtis Doty]

Is fast bootup a priority for other Fedora server admins?

I know this may be an exercise in futility on popular server-class 
hardware where the BIOS takes an inordinate time finding its boots. :-( 
But when we run server clusters on cheap/desktop-grade hardware, the added 
few seconds is quite significant for HA scenarios.

I've submitted a few bugs/patches that shave off a few more seconds on a 
minimalist f10 setup.

  http://bugzilla.redhat.com/327661 - net optional BLINDSTART skips arping
  http://bugzilla.redhat.com/327651 - postfix smart newaliases
  http://bugzilla.redhat.com/475101 - ipmi high-res sleep for udev

Time to prompt is reduced from 19s to 12s here. And no more large 
steps/delays appear in bootchart. Should these block FedoraServerTracker?
