On Linux, are you doing this using LVM? I know LVM lets you set up
mirrors on a logical volume-by-volume basis, which is what allows
multiple filesystems to be independently mirrored. To do the
equivalent on Mac OS X would require Apple (or a third party) to port
the open-source LVM package to Darwin.
I would personally LOVE to see LVM on Mac OS X, at least as an option
for the server OS, as it would bring much of the flexibility in
filesystem and disk management that other UNIXes enjoy to the platform.

Jay,
Well if multi-filesystem RAID-1's aren't possible under
MacOX X then it certainly has a more limited RAID implementation
than Linux. I have set up RAID-1 mirrors on Fedora Core 2 using
the software RAID support and there is no limit to the number
of filesystems on a given disk that can be RAID-1 mirrored. For
example you can have /boot, /, /var and /home all mirrored
on the same disk with each having its own ext-3 partition.
One would hope that MacOS X's RAID implementation would be at
least as capable.
