Few pending handbook updates

Hi guys,

In bug #369841 [1] I have a set of updates to the handbook ready in a single
patch. The patch does include quite a few changes based on end-user feedback
received earlier. If you'd rather see it as separate patches, just yell.

If okay, i'll focus on the bugs associated with the openrc/baselayout-2
tracker [2] so that we can get this openrc/baselayout-2 over with ;-)
