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?)
