With my SRU/TB hat on, I'd prefer making individual changes to e. g. mysql and other packages rather than changing this wholesale. Even if we did review all packages in Ubuntu which ship an init script that still leaves third-party scripts (and there are a lot of them). So I strongly recommend not to change the LSB package itself.

Despite the good intentions, that never actually taught people about the correct interfaces. Now with the advent of co-installability of multiple init systems, users may have systemd, upstart, and sysv-init all installed on users system and have init.d scripts / upstart jobs / systemd units all available. To avoid any doubt, we should support executing /etc/init.d/ scripts which may call into upstart, or into systemd, or actually execute the script in question depending on whether there is native configuration for that particular job and which init system we are running under. [ test case ] Invoking init.d script should invoke upstart commands, for example: $ /etc/init.d/ssh status ssh start/running, process 4620 $ /etc/init.d/ssh stop stop: Rejected send message, 1 matched rules; type="method_call", sender=":1.2469694" (uid=1000 pid=3908 comm="stop ssh ") interface="com.ubuntu.Upstart0_6.Job" member="Stop" error name="(unset)" requested_reply="0" destination="com.ubuntu.Upstart" (uid=0 pid=1 comm="/sbin/init") $ sudo /etc/init.d/ssh stop ssh stop/waiting $ sudo /etc/init.d/ssh start ssh start/running, process 5373 $ sudo /etc/init.d/ssh restart ssh stop/waiting ssh start/running, process 5405 Description: Ubuntu 13.10 Release: 13.10 mysql-server-5.5: Installed: 5.5.35-0ubuntu0.13.10.1 Candidate: 5.5.35-0ubuntu0.13.10.1 Version table: *** 5.5.35-0ubuntu0.13.10.1 0 500 http://us-east-1.ec2.archive.ubuntu.com/ubuntu/ saucy-updates/main amd64 Packages 500 http://security.ubuntu.com/ubuntu/ saucy-security/main amd64 Packages 100 /var/lib/dpkg/status 5.5.32-0ubuntu7 0 500 http://us-east-1.ec2.archive.ubuntu.com/ubuntu/ saucy/main amd64 Packages In Ubuntu 13.10, the Upstart job and the init.d script do not work properly. In previous versions, the init.d script was a symlink to the wrapper script around upstart (/lib/init/upstart-job). This conflict means that if the server was started using the init.d script, upstart does not recognize that the server is running and will attempt to start a second instance of mysqld. Also problematic is that if the upstart job is started using the service or start commands, the init.d script's "stop" function runs a mysql shutdown, but upstart simply restarts mysqld (because it's marked respawn in the upstart config). Description: Ubuntu 14.04 Release: 14.04 mysql: mysql-server-5.5.43-0ubuntu0.14.04.1 The problem in some setup was that the upgrade von 12.04 to 14.04 requres the adjustment of the InnoDB log size. Therefore the start of MySQL via upstart failed directly while the one via init started successfully and then failed as below. r...@webserver01.kurt..ref:~# status mysql mysql start/running, process 5866 r...@webserver01.kurt..ref:~# /etc/init.d/mysql stop * Stopping MySQL database server mysqld [ OK ] r...@webserver01.kurt..ref:~# status mysql mysql start/running, process 6101 r...@webserver01.kurt..ref:~# /etc/init.d/mysql status * /usr/bin/mysqladmin Ver 8.42 Distrib 5.5.43, for debian-linux-gnu on x86_64 Copyright (c) 2000, 2015, Oracle and/or its affiliates.

This is horrible. The "status" commands report the wrong status and the start/stop commands do not work. If our operators are not super careful, our orchestration and monitoring system will go wild, report the wrong status and/or perform continuous restarts of the system as they think the service is not running. So we also fix it in trusty. the result will looks as below: ubuntu@maas:~/work/deb$ sudo start mysql mysql start/running, process 8523 ubuntu@maas:~/work/deb$ sudo status mysql mysql start/running, process 8523 ubuntu@maas:~/work/deb$ sudo /etc/init.d/mysql stop mysql stop/waiting ubuntu@maas:~/work/deb$ sudo status mysql mysql stop/waiting ubuntu@maas:~/work/deb$ sudo /etc/init.d/mysql status mysql stop/waiting [Regression Potential] * Some scripts call '/etc/init.d/<service> reload' will not work if upstart script lacks a reload function and the reload function of /etc/init.d/<service> also uses PID. because it's managed by upstart now (the PID file does not exist). We should enumerate all those bad scripts and make them do the correct thing.
