If your kernel has support for the Amiga partitions, this works,
not just with /dev/loop7 but also with regular files:

sudo kpartx -v -a /dev/loop7

This will show which (-v) and add (-a) partitions, which will
then be named /dev/mapper/loop7p1 etc. (yes, /dev/mapper), but
this is a generic solution, you can do this with LVM LVs or
even files too ;-)

But mind #680672 (although this bug is probably due to missing
partition map in the kernel…?).

You could also just dd the Debian/m68k ext2fs image onto the
partition (using dd’s “seek” parameter), then resize2fs it
to your needs. (Although ext4 is probably better. Do *not*
forget the “p” parameter to tar when extracting it!)

<igli> just about the worst way you could do something like that, afaic.
<igli> it's like anti-design.  <mirabilos> that too… may I quote you on that?
<igli> sure, tho i doubt anyone will listen ;)
