Bug#825913: systemd init script integration: needs manual systemctl daemon-reload after installing initscript

[Chris Wilson]

Package: systemd
Version: 230-1
Severity: normal

Dear Maintainer,

I installed Nagios from source, including an init.d script, but this script
mysteriously failed to start Nagios.

When installing packages from source, it is normal to install an initscript in
/etc/init.d.  These scripts no longer work in Debian >= Jessie because
/lib/lsb/init-functions.d/40-systemd intercepts their execution and tries to
make systemd start the service, but systemd-sysv-generator has not been invoked
to generate a service file for it yet, so systemd cannot be used yet.

The failure of traditional initscripts defies expectations of backwards
compatibility by invoking magic (in 40-systemd) which does not work in this
case.

Workarounds are to manually execute "systemctl daemon-reload" (which runs
systemd-sysv-generator in a special way) or reboot the system, which generates
these service files, but it's not clear from the error that either is
necessary, since it just says:

    [....] Starting nagios (via systemctl): nagios.serviceFailed to start
    nagios.service: Unit nagios.service failed to load: No such file or directory.
    failed!

Jessie's 40-systemd script automatically invokes "systemctl daemon-reload" but
only when run from a dpkg install. Even this backwards-compatibility measure
seems to have been removed in unstable.

Please consider invoking "systemctl -p LoadState show $service" from 40-systemd,
and if it says "not-found" then run "systemctl daemon-reload" to generate a
service file for it.
