This bug is related to #426877:
"dpkg: Option "--oknodo" should be the default behaviour for "start-stop-daemon" (LSB specs)"
Acording to the LSB specifications for init scripts :
"For all other init-script actions, the init script shall return an exit
status of zero if the action was successful. Otherwise, the exit status
shall be non-zero, as defined below. In addition to straightforward
success, the following situations are also to be considered successful:
- Restarting a service (instead of reloading it) with the force-reload
- Running start on a service already running
- Running stop on a service already stopped or not running
- Running restart on a service already stopped or not running
- Running try-restart on a service already stopped or not running"
But the /etc/init.d/skeleton says:
# 0 if daemon has been started
# 1 if daemon was already running
# 2 if daemon could not be started
# 0 if daemon has been stopped
# 1 if daemon was already stopped
# 2 if daemon could not be stopped
# other if a failure occurred
They should return 0 when "start" even if the service was already running and return 0 when stoping it even it was already stopped.
I think the policy should change to be LSB compliant:
- "skeleton" script should incite the LSB behaviour.
- "start-stop-daemon" should use "--oknodo" but default (see bug http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=426877).
- A lot of services in Debian not using skeleton or start-stop-daemon should make correct the return values according to LSB specs.
