Actually, if you're not doing anything with block sizes...
you can merely do:

cp /dev/sda1 root.ext2

mkdir /tmp/tmpmnt
mount -o loop root.ext2 /tmp/tmpmnt
ls /tmp/tmpmnt
umount /tmp/tmpmnt

If you copy an entire disk using this method...
e.g. cp /dev/sda sda.disk
Then you'd have to supply offsets to go to the
filesystem you wish to mount (man losetup and look
for offset).  A loop mount can take an offset=
option.
