Bug#411943: partman-lvm: inconsistent usage of unit symbols for, decimal and binary multiples
I think this bug is quite high priority and should definitely be fixed
for Lenny. I recently installed from a debian installer snapshot and
manually partitioning LVM was nearly impossible. It may not make much of
a difference when you're partitioning 20 GB or so, but the drive I was
partitioning was 300 GB. You're forced to play "guess and check" and
given the inefficiencies of a text installer it's painful.
I ended up partitioning in a spare rescue cd I had and then restarted
the whole installation process, completely bypassing the whole issue.
