here I've mixed two things together: with disk emulation you neither can
create the partition on host (because atari_fdisk doesn't support disk
images) nor you can create the filesystem from host easily (unless you
guess the partition offset for the loop offset parameter or have the
Laurent's 2.6.26 kernel with Atari partition support compiled in).

from inside of the ARAnyM linux-m68k, naturally:

And there could be case C) dedicate spare disk partition or whole disk
drive to ARAnyM

1) c/s/fdisk /dev/sdX to create as large partition you want to dedicate

the rest is same as with disk image, i.e. map the path and run mke2fs in
any of the host/guest system.
