Well it doesn't need udev itself, just libudev.
But if the binary blob is hard-coded to search for
/usr/lib/libudev.so.0{,.9.3}, that means /usr must exist at
boot-time...
... or at least /usr/lib/libudev.so.0{,.9.3}
IMO, providing 1 file (+ 1 symlink) is still much better than having
to provide the *whole* /usr tree during boot-time.
Now, what's needed is to "catalog" (1) essential boot-time devs that
can't be handled by mdev, and (2) essential files that need to exist
under /usr during boot-time.
#1 should be interesting for busybox upstream, while #2 will be
necessary for those trying to wean themselves off udev :-)
We're one step closer to an udev-free Gentoo, yay!
(Come to think of it, has *any* distro ever attempted this...
'unconventional of going udev-free?)
