Alpine Linux

I cannot reproduce.

From your output:

• Starting Kamailio...
• start-stop-daemon: /usr/sbin/kamailio is already running [!!]
• ERROR: kamailio failed to start

Maybe kamailio alread was running at this point?

fs:~# rc-service kamailio zap

• Manually resetting kamailio to stopped state

'zap' does not stop anything. It just tells openrc: "this service is stopped because I say it is, no matter what you think or if it really is"

fs:~# rc-service kamailio stop

• WARNING: kamailio is already stopped

openrc thinks the service is stopped due to it was told it was. Since it was told the service is stopped (no matter if actually was)

fs:~# rc-service kamailio start

• Starting Kamailio...
• start-stop-daemon: /usr/sbin/kamailio is already running [!!]
• ERROR: kamailio failed to start

Well, if kamailio was running in first place (as message indicated) then this message is correct. The 'zap' doesnt try stop anything.

Try this:

rc-service kamailio stop # ask openrc to stop it
killall kamailio # actually kill kamailio if the above didnt work
pidof kamailio # check that there are no running kamailio
rc-service kamailio start

ok i can reproduce now. the problem is that the group 'kamailio' is not there and the pre-install script is never executed.

Will fix this.

Thanks!
