Well, ok, I neglected to mention that when I first bought the disk and did
the first rsync, I booted from a slackware CD and ran lilo on the disk one
time. After that, it's bootable.

Yes, I would have to change one mount point in fstab. Fooey on you! But in
terms of OS+data, it's an exact mirror that functions properly, which is
really sweet, especially from a single command.

Yep, one big one. Standard ext3 except that I tune2fs-ed it, to reduce the
reserved blocks percentage from 5 (the default) to 2, which gains me about 7
gigs (on a "249GB" partition, originally df reported 222GB usable, and after
tune2fs-ing it, there's 229GB usable).
