 Because eudev is already installed mostly in / - as I said, even if libudev.so
is installed in /usr/lib, there's still a symlink created to point to it from
/lib. Same for udevadm: installed in /usr/bin but a symlink is created from
/bin. Basically, it's eudev itself that decides it should be in / in addition to
/usr.

 That said, I don't think David's use case is one that we should support,
because IMHO it's the wrong way to go at it. I think it's better to make a
separate full filesystem and either pivot_root or union-mount it. I think
depending on the /bin or /usr/bin location is a recipe for disaster.

 Arnout
