i may regret asking this if i suddenly realize how to do it after i hit ENTER but i still don't see a simple way to do this. for booting beagleboards and pandaboards, one normally uses an SD card that is formatted as a tiny hard drive -- there's a partition table, an initial DOS partition, and the rest of the card is typically an ext2 or ext3 partition containing the root filesystem. if i have a byte-for-byte image file for the SD card, is it possible to mount one of those internal filesystems? i'm well aware of the "-o loop" option for mounting image files, but now i want to mount a filesystem that's *inside* such an image file, so i can make changes to it. can i do this? am i missing something stupidly obvious? rday -- ======================================================================== Robert P.
