When Discover reports an upgrade with system implications (say a new kernel) and the user allows the upgrade (by clicking the appropriate button):
  1. Discover downloads the files for the upgrade
  2. Discover requests a reboot.  After the user allows the reboot
  3. Discover reboots the system
  4. Discover installs the new kernel (or whatever)
  5. Discover reboots the system (again)
What is the reason for the additional reboot before installing the new kernel (step 3)?

	Dance, as if nobody's watching,
	Love, as if you've never been hurt,
	Sing, as if no one can hear you,
	Work, as if you don't need the money,
	Live, as if heaven is on earth.
