The fix is very simple. The idea here is that a library from / which needs
something from /usr can have some problems while being on systems where /
and /usr are on different partitions and /usr can be unavailable at an
early stage. The obvious fix would be to move libgudev in /usr but before
doing this we need to be sure that nobody needs this in the early stages of
booting.

I would love to see this warning addressed.
