Most intersting. Option 3 does both un-mirrored and mirrored. I'm not
sure I want to test that one out, but sound plausible. I guess I'm good
with putting swap on an un-mirrored partition, as long as it doesn't
break the mirrors in the event of one disk failure, (see my post a few
minutes ago on this). Seems un-mirrored would be faster anyway, but I
want to keep the integrity of the mirrored partitions.
