Many thanks! This will allow us to package the current udev.

Please note that we wouldn't use an epoch but a carefully crafted
un-epoched version number, otherwise we'd have to keep it forever when
we switch back to kmod the second time. As m-i-t is abandoned upstream
(kmod is the official successor), I don't see us permanently
reverting; kmod has been out for a rather long time and should be
fairly stable.

AFAIK these were used by ancient hotplug versions to find kernel
modules. This has been replaced long ago (modprobe/udev, etc.) by the
binary maps which are a lot more efficient.

Great, thanks!
