This is definately NOT a good solution. A journaling FS and ext2 can be
used simultaneously, no? This means that I could theoretically use both
ext2, ext3, and software RAID at the same time, if I had all of the
patches applied. I would rather have one of them stay as a patch, and
not have some kludge of an if statement from doing something that I know
is perfectly safe.

RAID 5 is there, it just sucks. As do RAID-0 and RAID-1 on NT (I speak
from expierence).

Yes, it is. Although maybe they use a different name for it. It does
keep a transaction log, and tends to be a reasonably robust filesystem
(compared to ext2 and FAT).

NTFS gets more use than software RAID because it offers SOOO much more
than FAT. Permissions are probably as big, or bigger than the fact that
NTFS is jounaling. NTs software RAID is unuseable because it doesn't
work, and because it was created at a time when NT machines didn't have
the kind of raw processing power to keep up with it very well.
