 Seriously, mdev is a just a bad and now useless hack, it does nothing
 more than using devtmpfs. You do not need udev for a very simple system.
 If you system is a bit more complicated, than udev is what you want. It
 works fine on millions of shipping devices.
 
 And on any new embedded platform, one should seriously think about using
 systemd too. It is very lean, replaces most of the giant, unmaintainable
 shellscripts that you find in many devices with smaller compiled code,
 and was designed to be a good fit for embedded devices.

Last time I looked at systemd it was anything that lean.

Obviously you can say that if you already need dbus and glib and ...
${systemd_deplist} it doesn't count.

Likewise if you are already using busybox it comes with a quite rich shell.

Most depends on what you consider embedded.

 A lot of that is optional. The only hard dependencies are:

 =sys-apps/kmod-5
 =sys-apps/util-linux-2.20
 dev-util/gperf
 =dev-util/intltool-0.40.0
 virtual/pkgconfig
 virtual/os-headers

 Everything else is optional. I repeat: the idea that udev is somewhat
 bloated or fat is really incorrect.

 Little correction: inherit autotools brings things like automake and
 libtool, but then again, almost *every* Gentoo installation has those.

build dependencies should not count. =)

The bare udev shouldn't be that huge, then you start look at the glib
integration and such and it might get a bit more than you'd like.

Forking udev and making sure it stays as lean as possible isn't that bad.

Making mdev a bit richer and enjoy the speed advantage of busybox over
stand alone shells could be another option.

Most of the perceived speed in non-shell init systems is due not having
to spawn as many processes. A full busybox wouldn't spawn many processes.
