I know how to mount an ISO as a loop device onto the file system, but if you'd be so kind, can you give a super-brief description on how to get a loop device to look like an actual partition that can be made into a RAID array? I can see this software-only solution as being quite interesting for testing in general. -- Moshe Yudkowsky * moshe@pobox.com * www.pobox.com/~moshe "I'm very well aquainted/with the seven deadly sins/ I keep a busy schedule/ to try to fit them in." -- Warren Zevon, "Mr. Bad Example"
