Well, I've been using Debian since Potato but before that I was using 
other distributions so yes, I do go back a ways. However being able to 
boot from a RAID 5 partition isn't the same as being able to boot from a 
partition on a RAID 5 array.  I believe you could do the former at least 
one version before you could do the latter.

LVM to me is more like a solution looking for a problem. Back when disk 
space was at a premium, the ability to reallocate it was important. 
However these days it's often easier to just to throw more hardware at 
it. It seems to me also that BTRFS makes LVM obsolete, so that I may 
have successfully avoided learning a technology that I will never need - 
assuming BTRFS ever gets optimized enough to compete with Ext file systems.

Obviously my use cases aren't the same as yours. You find that LVM 
solves problems for you. I have yet to encounter a situation where I 
said "I wish I'd installed LVM".
