correction: The point is, if you want to re-execute make_prepare(),
(deleting the lock file made by run_once()), do it on the same "state"
of untouched workdir, since _cleanup removes files and maybe you want to
re-exec pacman, was good for testing purposes... can be removed, indeed
# rm ... /airootfs can be uncommented....


I am currently working on this idea of single sfs ;)
