I have a squash file, say ABC.sqsh which is created from;
dir-1, dir-2, dir-3, etc.
If dir-2 has been changed with files added or deleted. Instead of creating a new ABC.sqsh with;
mksquashfs dir-1, new-dir-2, dir-3, etc. new-ABC.sqsh. Is there a way adding files to OR deleting files from the original ABC.sqsh ?
