 That's a very good motivation!

 So you're generating a rootfs with empty /etc? Do you need any other changes to
make that work? To support this use case, it would be nice if we could add an
option to the system menu that enables it (this would depend on systemd of
course), so that it can be used fo force packages to do whatever is needed to
support empty /etc. And then we can add a post-build check that /etc is really
empty at the end of the build, so that the autobuilders can detect problems.
