Package: dmucs
Version: 0.6.1-2.1
Severity: important
I've been wondering for years why dmucs never worked in my network.
Finally traced the start scripts:
if start_server && server_running ; then
...
if start_loadavg && running ; then
start_server and start_loadavg don't create a valid PID file for some
indeterminate time after start-stop-daemon fork off a dmucs/loadavg
process.

Bugger. Bails out with failure message instead of continuuing on to
start loadavg.
A quick "fix" is to:
if start_server && sleep 5 && server_running ; then
...
if start_loadavg && sleep 5 && running ; then
but surely there's a better way (eg, remove the test entirely, since
I've never seen any other init script do something like this).
