[Message part 1 (text/plain, inline)]

I had some time to check the sources of eudev and it does not contains
the f59118e commit, that prevented the removal of the control socket on
exit[1], so I send this patch to restore the old rock solid start-up
behavior of udev

the patch is based on the Devuan unstable ed8c5770e0 commit, but please
note that it is untested, as i don't have a Devuan system, nor eudev,
but at least it shows how to do it

basically eudev is launched with --daemon argument and all the pidfile
tracking stuff is removed, because when eudev is killed by sendsigs, it
removes the control socket and dmsetup/cryptsetup will not hang trying
to connect to eudev on shutdown

ciao!
