Tiny Ext(2/3/4) Images

The images are of size 64Kb which supports 64 1k blocks and 16 inodes. This is the smallest size mkfs.ext(2/3/4) works with.

These images were generated using the following commands.

fallocate -l 64K tiny.ext$VERSION
mkfs.ext$VERSION -j tiny.ext$VERSION

where VERSION is 2, 3 or 4.

You can mount it using:

sudo mount -o loop tiny.ext$VERSION $MOUNTPOINT

file.txt, bigfile.txt and symlink.txt were added to this image by just mounting it and copying (while preserving links) those files to the mountpoint directory using:

sudo cp -P {file.txt,symlink.txt,bigfile.txt} $MOUNTPOINT

The files in this directory mirror the contents and organisation of the files stored in the image.

You can umount the filesystem using:

sudo umount $MOUNTPOINT
