You can try something like losetup -o OFFSET /dev/hda /dev/loop0 mount ... /dev/loop0 ... You can't (as far as I know) set the length of the loop device, so you'll have to trust the filesystem's code to behave (most do). -- Didi ================================================================= To unsubscribe, send mail to [EMAIL PROTECTED] with the word "unsubscribe" in the message body, e.g., run the command echo unsubscribe | mail [EMAIL PROTECTED]
