You need the minor number so the driver knows which instance of the device. Anyway - just remember that there is a set limit on the maximum number of loop devices which can be created. The default is usually fairly low, probably depends on the specific distro, and can be set to a different limit as a parameter to the module. --Amos -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
