supermin can not be used in a chroot when called as builduser, because
there is no repo configured inside that chroot.

supermin need to handle the case '--root X --reposd-dir Y', which is
triggered by the '--packager-config <conf>' option. Currently the <conf>
file is expected in X//<conf>, which will fail. 
The new code has to parse <conf>, look for reposdir=<dir> and replace
the current hardcode path Y with the one from <conf> so that libzypp
continues to oerate below X (--root X --repos-dir <dir>).

I think there is some odd ocaml-iniparser package, which I could use.
Or I just grep for reposdir= and use that.

I dont know much about the underlying libsolv, its very likely that in
the end libzypp does all the required work.
