You know what's cleaner than that?  git revert 27d6ec7ad
It has just been merged; until 3.19 it's fair game for removal.

And yes, I should've NAKed the damn thing loud and clear, rather than
asking questions back then, getting no answers and letting it slip.
Mea culpa.

Back then the procfs-free environments had been pushed as a serious argument
in favour of merging the damn thing.  Now you guys turn around and say that
we not only need procfs mounted, we need a yet-to-be-added kludge in there
to cope with the actual intended uses.
