Sure, but the general point applies.

Just to be clear, I wasn't calling mdraid "silly", I said that
partitioning and software raid has silly limitations - which it does.

E.g., why have primary partitions? why extended ones? Why can I only
have 4 primaries? Why do partitions have to be tied to physical
hardware? Why is it so hard to move/resize partitions? etc. etc.

LVM gives you all the features you're used to, doesn't have the same
limitations, and gives you many, many more features you don't have. For
example, if you wanted to install a new hard drive: you can plug it in,
move your partitions across live, and then deactivate the old hard
drive. You could resize those partitions while you're doing that,
reorder them, whatever you want to do. 

I think you'd enjoy LVM: it's simpler than mdraid, and much more
flexible. 

Cheers,

Alex.
