[Pkg-sysvinit-devel] Bug#856044: sysvinit: Any update-rc.d command executed in dry-run mode causes a 'systemctl daemon-reload'

[Stefano Rago]

Package: sysvinit
Version: 2.88dsf-59
Severity: normal

Dear Maintainer,


   * What led up to the situation?
	Several of the Debian Jessie machines in our infrastructures are running Chef as configuration management system. Part of the provisioning process involves running commands like 'update-rc.d -n -f <service_name> remove' whose output used to determine the status of a certain managed service.
	This is supposed to be a dry-run command, but it issues a 'systemctl daemon-reload' with undesirable side-effects, at every provisioning.

   * What exactly did you do (or not do) that was effective (or
     ineffective)?
	I managed to figure this out running this command:
		strace -f -e execve update-rc.d -n -f apache2 remove

   * What was the outcome of this action?
	the following stacktrace:

execve("/usr/sbin/update-rc.d", ["update-rc.d", "-n", "-f", "apache2", "remove"], [/* 29 vars */]) = 0
Process 9413 attached
[pid  9413] execve("/sbin/insserv", ["/sbin/insserv", "-n", "-f"], [/* 29 vars */]) = 0
insserv: dryrun, not creating .depend.boot, .depend.start, and .depend.stop

   * What outcome did you expect instead?
	that the 'systemctl daemon-reload' command is not issued as part of the dry-run
