upon mounting the /casper/filesystem.squashfs, I found out that
the file still contains 700+ MB of free space.

What if,

1. mount the squashfs.
2. copy the squashfs to a 3GB loop ext2 file.
3. finish modifying the loop ext2 file.
4. check the disk usage of the loop ext2 file.
5. create a new loop ext2 file with >= disk usage of the loop ext2 file.
6. copy the old loop ext2 file to the new loop ext2 file.
7. create the squashfs based on the new loop ext2 file.

I haven't tried this yet, and I know that the disk space are marked zero's
by /dev/zero,
does creating the exact disk usage for the squashfs makes any difference on
the filesystem.squashfs filesize?
