Tomas, Sorry to repeate myself --
i) aufs has nice README files, just try to believe them ii) I've been asking the same question in this mailing list so google may help you. Actually Okajima-san redirected me to the README file and my problem was immediately solved. BTW, GNU make has dry-run, debuging, force build, and many other nice features. Using a dry-run won't remove any of your system files, and you can do it as an unprivileged user. But if your time is precious (yes, i fully comprehend. i saw your posts on slax forum about hard life), then no need to dig things up.
