'up' is only partially helpful here. You can either have 'up' stop copying
at mountpoints, so you're only copying the part of the tree that's in an
individual volume, or you can have it copy the entire tree below some
point, in which case mountpoints in the source become regular directories
in the target, and everything gets "pulled up" into the target volume. I
rather imagine that's where the name "up" comes from, but I don't really
know. It's saving grace of course it that it copies ACLs as it goes.

I don't think 'up' will detect or avoid endless loops, but it's been a
while since I've been in that part of the code.
