is there a way to mount and access a single partition on any mountpoint in my filesystem or must I use disk images and mount with offset?I made a partiton image with dd bs=4M if=/dev/sdb1 of=~/part.img and tried to mount it on /mnt with mount -t vfat ~/part.img /mnt.The output of mount is an Unknown Error -1
mounting partition images made with dd
mount;dd;disk image
Yes, it is perfectly possible to mount partition images made with dd.  You should add a -o loop (i.e., use a loopback device) to the mount command.The final command should look like:mount -oloop -t vfat ~/part.img /mntOf course, you should have dd'ed from a valid and previously formatted vfat filesystem in the original partition.
