It makes more sense to mount it where it is first used (udev).
Hmm. Should that apply to /sys and /run and /proc then as well?
It is definitely true that nothing uses /sys until udev starts (hmm, and
maybe not even udevd uses it; it might only be "udevadm trigger").
I don't believe anything uses /run until udev either (there are no earlier
daemons, at least, which doesn't necessarily prevent anything from using
it, but it seems likely).
It seems consolelog uses /proc, but then the mounting of /proc should be
moved there. :-)
OTOH, many other scripts also use stuff in /proc, so to avoid having them
all depend on consolelog, it makes more sense I think to leave /proc where
it is. But then for consistency we should move the other virtual FSes
(/sys, /run, and now /dev) into that script as well, and depend on it (via
the Required-Start: header, which enforces an ordering on an LSB setup,
not via anything that sysvinit currently does) from the places that need
any of them.
(Lots of scripts run programs that use /dev -- udev is the obvious one,
but also swap, checkfs, cleanfs, mountfs, udev_retry, sysklogd, and maybe
a bunch in BLFS. Some of these care about the modifications udevd will
make, but for example sysklogd does not. It just creates the /dev/log
socket.)

Note also there are a few broken network drivers with udev-176 (...and I
thought Kay knew about the presence of these before he committed the patch
to remove timeout handling, but either he didn't, or he committed it
anyway):

We might need a newer kernel, to get the fixed drivers.
