[PATCH] udevd - switch socket path to abstract namespace
As Chris Friesen <chris_friesen@sympatico.ca> suggested, here we switch
the unix domains socket path to abstract namespace and get rid of the
socket file in the filesystem.
Hey, this was new to me today. So here a few words:
Linux supports a abstract namespace for sockets. We don't need a
physical file on the filesystem but only a unique string magically
starting with the '\0' character.
strace with real file:
connect(3, {sa_family=AF_UNIX, path="/udev/.udevd.sock"}, 110)
strace with abstract namespace:
connect(3, {sa_family=AF_UNIX, path=@udevd}, 110)
