# in another net namespace and managed by libvirt, Docker or the like.
# Generally we don't want to mess with those. One exception would be the
# full system containers, like LXC or LXD. LXC containers run via libvirt
# don't use udev, so this doesn't apply. LXD does, though. To deal with the
# LXD situation, let's treat the devices called eth* as regular ethernet.
