You can create a file system in a file within the current file system on linux.
1. Creating an initialized file
dd if=/dev/zero of=/tmp/fstest.img bs=1024 count=5000
file /tmp/fstest.img
losetup /dev/loop0 /tmp/fstest.img
2. Creating an ext2 file system with the loop device
mke2fs /dev/loop0
file /tmp/fstest.img
3. Creating a mount point and mounting the file system through the loop device
mkdir /mnt/fsttestimage
mount /dev/loop0 /mnt/fstestimage
df -h /mnt/fstestimage
cd /mnt/fstestimage
ls
mount -o loop /tmp/fstest.img /mnt/fstestimage/
dumpe2fs /tmp/fstest.img
