  If you are not running systemd, then eudev is the preferred udev
implementation.  Binary distros can build systemd, extract udev on a
developer's machine and package it like a library.  Gentoo, being
source-based, has to do some hackish workarounds, installing, and then
removing, much of systemd on the user's machine with every update to
udev.  Lennart Poettering has made no secret that he's chomping at the
bit to get rid of standalone udev.  Even more ominous is the following
