First, create a file for your loopback (This will make a 10 meg file):
dd if=/dev/zero of=myloop bs=1048576 count=10
Now put a filesystem on it:
mke2fs myloop
now just mount it:
mount -t ext2 -o loop=/dev/loop1 myloop /mnt
Now just use it like you would any other filesystem. You'll get a
couple of warnings with the above commands (like myloop not being a
regular block device), but it will work.

1. Is loopback-based FS slower than normal FS?
Is a filesystem based on the new loopback (not to be confused
with the loop back device related to TCP/IP networking) device of Linux
v2.0.0 slower, faster, or just the same as a "real" (i.e. on a real
partition on the HD) filesystem?
I ask this because I got an idea for users using the UMSDOS
filesystem. I'm thinking people use UMSDOS 'cause they don't want to
repartition their drives. The price they pay for using UMSDOS is a
slower filesystem, and wasted disk space due to the way FAT stores data.
I'm thinking, that UMSDOS users can mount a ext2fs formatted
loop-back based filesystem as thier /usr filesystem. Would this offer
any advantages? Assuming that using a loopback device is just as fast as
using a real partition, there would be a speed advantage. Also, storage
efficiency may be increased; just make the size of loopback file a
multiple of cluster size.
Comments please .....
