To create a simple "tinyfs.gz" image (containing busybox,
sudo, the needed libraries, and some boot scripts) you can
use the "BuildCore" scripts:
	git clone https://gitlab.retis.sssup.it/l.abeni/BuildCore.git
	mkdir TinyFS
	cd TinyFS/
	sh ../BuildCore/buildcore.sh $(pwd)/tinyfs.gz


To update this image (adding some files to it), create a
new cpio file by putting what you need in a directory,
and then running
	find . | cpio -H newc -o | gzip > ../mod.gz
from inside the directory. For example, to add a module
named "module.ko" to the image you can use
	mkdir Tmp
	cp module.ko Tmp
	cd tmp
	find . | cpio -H newc -o | gzip > ../mod.gz
	cd ..
The resulting ".gz" file can be concatenated with tinyfs.gz.
For example,
	cat mod.gz tinyfs.gz > test.gz
