You can already use Device-Mapper to create "partitions" on your loop devices, so there's not much of a reason to add partitioning support to the loop driver itself. There are a variety of tools you can use to set them up: EVMS, LVM2, dmsetup, and I think there is/was a simple partitioning tool that uses DM (dmpartx?). -- Kevin Corry kevcorry@us.ibm.com http://evms.sourceforge.net/
