Good hint, thanks.

That would be great.
fuser /dev/lircd
could do the trick: it returns 0 if the socket exists and is in use, and
1 if the socket does not exist or is not in use.
Small patch attached. A little bit dirty, but it works :) It does not
work if somebody configures -d in /etc/default/inputlirc to a different
socket name - parsing things like
-d /dev/foo/bar
-c -d /dev/foo/bar -f
-cd /dev/foo/bar -f
in shell is not that nice - works, but ... :)
