Well, first of all, the installer can handle mirrored /boot's since ages,
so you can mirror /boot too.  Second, you can mirror swap too, although
I agree it doesn't make sense on non-hot-swappable IDE drives (but it
*does* make sense to do so on hot-swappable SCSI drives, as you're
otherwise still lost when one of the two drives gets problems).

/usr is 1 GB, which is *very* small, the rest at first sight looks ok.
Unless you do a minimal installation, thsi probably won't fit.

It can since ages (RH 8.0 or so, IIRC), although it could be a bug in
the FC2 test release (didn't try that myself).
