Clone project
Checkout all branches that contain the files that should be moved
Delete the remote

Run the filter-branch command:

git filter-branch --tree-filter 'mkdir -p /path/to/tmp; mv * /path/to/tmp; mkdir subdir; mv /path/to/tmp/* subdir/' --tag-name-filter cat --prune-empty -- --all

All files are first copied to a temporary dir and move from there to the new destination

Existing tags are updated

	./scripts/create_fake_device.py --dest /tmp/daemon_test --all
	./scripts/create_fake_device.py --dest /tmp/daemon_test razerdeathadderchroma

	# other tab
	systemctl --user stop openrazer-daemon.service
	openrazer-daemon -F --verbose --run-dir /tmp/daemon_stuff/data --log-dir /tmp/daemon_stuff/logs --test-dir /tmp/daemon_test
	# run from source from testdata
	PYTHONPATH="pylib:daemon" python3 ./daemon/run_openrazer_daemon.py -Fv --run-dir /tmp/daemon_stuff/data --log-dir /tmp/daemon_stuff/logs --test-dir /tmp/daemon_test --config=$PWD/daemon/resources/razer.conf

	# copied from http://gbayer.com/development/moving-files-from-one-git-repository-to-another-preserving-history/
	git clone <git repository A url> # clone source repository
	cd <git repository A directory>
	git remote rm origin # to make sure it doesn't affect the original repository
	git filter-branch --subdirectory-filter <directory 1> -- --all # remove all files other than the ones needed
	mkdir <directory 1> # move them into another directory where they will be stored in the destination repository (if needed)
	mv * <directory 1>
	git add .
	git commit

	pacman -S wget # needed for debootstrap

	curl -o /tmp/db.deb http://ftp.debian.org/debian/pool/main/d/debootstrap/debootstrap_1.0.60~bpo70+1_all.deb
