partitions on loop or device-mapper devices ?

you can use kpartx tool for this.

bryn m. reeves told me, that it's probably poissible to create udev rules
that will automatically create partition maps when a new loop device is
setup, which is better than adding partitioning logig into dm-loop for
example.

example:
>kpartx -a /dev/mapper/loop0
>
># ls /dev/mapper/loop0*
>/dev/mapper/loop0 /dev/mapper/loop0p1 /dev/mapper/loop0p2
>/dev/mapper/loop0p3

i have seen a patch for loop.c doing this, though. search the archives for
this

Agreed. What would be a right way? Global device ala ptmx/tun/tap?
New syscall? Something else?
