[PATCH] 470733/452768 - save /etc/fstab on upgrades

[Chris Lumens <clumens redhat com>]

We now write out a new /etc/fstab on upgrade.  This has the unfortunate
side effect of any entries anaconda doesn't understand getting dropped.
After staring at it off and on all day, I can't see any way to fix this
that doesn't involve lots of fairly invasive changes so instead how
about if we just backup the fstab before writing out a new one?

I'm open to other suggestions.
