  I understand that one option being considered is patching the build to
not depend on files in /usr.  Showing my age here, I remember when IBM
patched Windows 3.1 on-the-fly, to make it a DPMI client of OS/2.  MS
released Windows 3.11, which vas very slightly different, and the patch
broke.  IBM had to rush out a new patch.

  Given how cavalierly Kay & Lennart broke firmware driver loading, I
would not envy the Gentoo ebuild maintainer trying to keep udev
compatable with a separate /usr, especially given Lennart's
pronouncement about standalone udev being "a dead end".  The maintainer
will face a task similar in principle to what IBM was doing.  What
Richard Yao is doing is the udev equivalant of "jump off before you get
pushed off".

We are apparently better off trying to avoid udev like the plague.
