just a stupid question :
Why does LVM2 was not a version of lvm so that we just had to upgrade LVM ?

If LVM2 is just an upgrade of LVM1, why couldn't you continue with lvm-xxxxx ?

It should have been less confusing and easier to upgrade. 

Sorry if it is abolutely stupid.

I'm using LVM1 and it works fine for me on a debian potato with a 2.4.18 
kernel with hardware RAID5 . Thank you for your work.
