Hi,
/lib/lsb/init-functions.d/40-systemd exports
_SYSTEMCTL_SKIP_REDIRECT=true to detect when it has been called
recursively again by systemd. This export is actually never cleaned up and
is passed to the daemon. In the case of Puppet, which uses “/etc/init.d
$service $action” (without cleaning up the environment - which is
probably an issue by itself) to query and change a daemon’s status, this
causes the init.d hook to not redirect the call to systemd. For services
that supply an actual systemd unit which does not simply call the init
script (e.g. clamav-freshclam) this can cause the action to fail.
A trivial fix would be:
> --- a/debian/extra/init-functions.d/40-systemd

But this doesn’t fix the case when systemd is not calling the init
script twice (because the service has an actual unit). Since the
approach to guard the recursion with an environment variable relies on
systemd not cleaning up the environment I’m not sure how to best fix
this.
