I find quite the opposite: without LVM, I have to know that the drive I
just moved from computer to computer changed from sdb to sdc, and edit
fstab and such manually.  With LVM, I still get /dev/vg_foo/lv_bar, and
don't care what raw device the underlying partition is, how it is
connected, etc. (very useful for example when taking an internal drive
from one computer and connecting it via an external adapter of some type
on another).
