cups.socket not working

Wiki says:
cups provides a cups.socket unit. If cups.socket is enabled (and cups.service is disabled), systemd will not start CUPS immediately; it will just listen to the appropriate sockets. Then, whenever a program attempts to connect to one of these CUPS sockets, systemd will start cups.service and transparently hand over control of these ports to the CUPS process.

Everything worked fine: socket was enabled, service was disabled and socket triggers the service on demand.
But after renaming update
https://github.com/archlinux/svntogit-p … 0e7193c9d0
socket works no more.
Yes, I reenabled it with new name, but no luck.

Anyone using cups.socket here?

Re: cups.socket not working

Whats the output of

$ systemctl status cups.service cups.socket 

Should look something like this (mine is a fresh install, though):

$ systemctl status cups.service cups.socket 

● cups.service - CUPS Scheduler

Works like expected.
