[Pkg-sysvinit-devel] Bug#774799: sysv-rc: Unit my-service.service failed to load: No such file or directory, using install from source + update-rc.d

[beuc at debian.org]

Package: sysv-rc
Version: 2.88dsf-58
Severity: important

Hi,

I'm currently working on the next version of FusionForge, which
installs a new service in /etc/init.d/ and starts it as part of the
installation process.

So I:
- Installed a new Debian 8
- git clone'd FusionForge and installed it
- Ran 'make post-install' which:
-- installs /etc/init.d/fusionforge-systasksd
-- detects Debian (not RedHat) and registers it using 'update-rc.d'
-- restarts the service using 'service fusionforge-systasksd restart'
(note: same result with 'invoke-rc.d fusionforge-systasksd restart')

Result:
Failed to start fusionforge-systasksd.service: Unit fusionforge-systasksd.service failed to load: No such file or directory.

Expected:
/etc/init.d/fusionforge-systasksd is executed

After searching the web to understand why on earth systemd dropped
compatibility with init.d, I eventually got advice from
#debian-systemd to just 'systemctl daemon-reload'.

It seems that update-rc.d does not tell systemd about the new init.d
script (and that invoke-rc.d only does so when
$DPKG_MAINTSCRIPT_PACKAGE is set).  FusionForge follows the Debian way
to install and activate a service, hence I expect it works without
having to introduce init-system-specific handling.

So, I suggest that update-rc.d tells systemd about the new init script
it just activated.

CC-ing pkg-systemd-maintainers at lists.alioth.debian.org as per request
on IRC :)

Cheers!
