===================================
# LANG=C parted -a none /dev/loop0
GNU Parted 2.1
Using /dev/loop0

=======================================

So, I guess, for losetup device, Parted aligns to the border of the
page (4096 bytes)

To make things easier, PLEASE interpret "END" parameter of mkpart
command as offset of the END of last accessible sector of this
partition. Today Parted interprets this parameter as offset of
BEGINNIG of last accessible sector in this partiton.


I think i'm not first who mention this behaviour. Please point me to
bug/documentation so.
