I'm afraid this causes do_package_qa errors in basic testing:

I am worried about this change as we're starting to see a number of
circular dependencies in util-linux (there is a new bug about the
pylibmount PACKAGECONFIG option too), maybe we should flag this
upstream?

Multiple recipes like this usually turn into a maintenance nightmare
unfortunately which is part of my reluctance to go in this direction,
not sure we have any choice though.

Cheers,
