Stopping it seems to work just fine:
# systemctl stop uuidd.service
#
# ps -C uuidd
   PID TTY          TIME CMD
#

The hang has to do with the non-extant /var/lib/libuuid/uuidd.pid
But, if you copy /run/uuidd/uuidd.pid (after starting it of course),
to /var/lib/libuuid/uuidd.pid, the hang goes away.
I did this using 2 gnome-terminals side by side.
in one I started uuidd, and in the other I waited a few seconds
and did
cp -f /run/uuidd/uuidd.pid /var/lib/libuuid/uuidd.pid

and the start command in the other terminal immediately
completes without error.

I think the coders need to make up their mind where
the pid file needs to be.
