[Pkg-sympa-devel] Bug#804066: Sympa logrotate leaves sympa service in a confused state

[Olav Morken]

Package: sympa
Version: 6.1.23~dfsg-2

After logrotate "reloads" sympa, systemd no longer considers the service 
as running.


/etc/logrotate.d/sympa contains:

     postrotate
         invoke-rc.d --quiet sympa reload > /dev/null
         invoke-rc.d --quiet rsyslog rotate > /dev/null || true
     endscript

When `invoke-rc.d sympa reload` is executed, it apperas that 
`invoke-rc.d` realizes that the systemd service configuration for Sympa 
(`/lib/systemd/system/sympa.service`) does not contain a reload action. 
It therefore ends up reloading Sympa through `/etc/init.d/sympa` 
instead. The result is that systemd becomes confused about the current 
status of Sympa:


$ sudo invoke-rc.d sympa status

At this point Sympa is running, but it is not running under the control 
of systemd. If for example Puppet later checks the status of Sympa, it 
will be told that Sympa is not running, and attempt to start it.
