Thanks. I just happened to be in the situation that I'm writing a guide
how to set up a minimal Debian/m68k system on ARAnyM from scratch.

Correct. I created an empty image, mapped it to /dev/loop0 using losetup
and ran my patched version of parted to create an Atari partition table
plus two partitions for the system and swap.
In ARAnyM, I had to enable byte-swapping as otherwise the partitions
were not recognized.

Wouldn't ARAnyM or a real Atari write the data byte-swapped to the
disk anyway? I would expect that parted just uses the host order
which is why I had to byte-swap the disk image when using it in
ARAnyM. But I think we could add the byte-swapping later if

Ok, good to know.
