This also involved a bunch of reindenting and rewrapping.
I reworked the Live CD sources on Debian to be more consistent with
Ubuntu (and the chroot sources configuration on Debian).
I reworked the zpool create wrapping and the mirror/raidz notes. This
should be more clear on how to create the multi-disk topologies.
I fixed a couple formatting issues too (mainly one backtick where
there should have been two).
