mount + шифрование

EXAMPLE
If you are using the loadable module you must have the
module loaded first with the command

# insmod loop.o

The following commands can be used as an example of using
the loop device.

dd if=/dev/zero of=/file bs=1k count=100
losetup -e blowfish /dev/loop0 /file
Password :
mkfs -t ext2 /dev/loop0 100
mount -t ext2 /dev/loop0 /mnt
...
umount /dev/loop0
losetup -d /dev/loop0

If you are using the loadable module you may remove the
module with the command

# rmmod loop


(C) man losetup
