Subject: [PATCH] multipathd: honor MULTIPATH_SOCKET_NAME environment variable
If multipathd is started via socket activation, it will obtain
sockets from systemd. The names of these sockets, and whether
the abstract and / or pathname socket is created, is configurable
in the systemd unit file.
Add support for passing a socket name via the environment, so that
it's possible to configure the socket name at runtime even without
socket activation. In this case, only this single socket will be created.
If creating the socket fails, multipathd startup will fail, too.
