Bug#262625: invoke-rc.d should be used

[Ognyan Kulev]

Package: gdm
Version: 2.4.4.7-3
Severity: serious

The following code is used in gdm.prerm:

if [ "$1" = "remove" ]; then
   nostop=
   for hostname in "" "localhost" "$(hostname)" "$(hostname -f)"; do
     if echo $DISPLAY | grep -q "^$hostname:0.*"; then
       nostop=yes
     fi
   done
   if [ -z $nostop ]; then
     /etc/init.d/gdm stop
   fi
fi

Debian Policy explicitly states that invoke-rc.d should be used: 
http://www.debian.org/doc/debian-policy/ch-opersys.html#s9.3.3

Many scripts look like:

# Automatically added by dh_installinit
if [ -x "/etc/init.d/apache2" ]; then
     update-rc.d apache2 defaults 91 >/dev/null
     if [ -x /usr/sbin/invoke-rc.d ]; then
         invoke-rc.d apache2 start
     else
         /etc/init.d/apache2 start
     fi
fi
