The dovecot packages on Debian Jessie do not seem to provide a systemd unit script. Instead systemd does a fallback to the LSB init scripts. This fallback seems to fail for the "reload" action.

Is there a possibility to disable the reload action of the dovecot service?

root@singlenode:/home/debian# /bin/systemctl reload dovecot
Failed to reload dovecot.service: Job type reload is not applicable for unit dovecot.service.

@kleini, thanks for the report.

I think we should disable it in that distribution version. Give me a couple of days, because there are no tests for that version.

[kleini]

Can you give me some hint how to solve that on my own? I tried to disable the reload support in the service but this does not seem to be sufficient:

service 'dovecot' do
  if node['platform'] == 'debian' && Gem::Version.new(node['platform_version']) >= Gem::Version.new('8.0') && Gem::Version.new(node['platform_version']) < Gem::Version.new('9.0')
    supports :status => true, :restart => true, :reload => false
  else
    supports :status => true, :restart => true, :reload => true
  end
  if node['platform'] == 'ubuntu' &&
     Gem::Version.new(node['platform_version']) >= Gem::Version.new('13.10')
    provider Chef::Provider::Service::Upstart
  end
  action [:enable, :start]
end

As a workaround I used now the systemd unit file for Fedora https://github.com/ioanrogers/systemd-units/blob/master/system/dovecot.service and put this into the system before installing dovecot.

@kleini something seems to be wrong with the Service#supports method. It does not work properly since the refactoring.

Thanks for the information, I'm going to try to fix the systemd script based on this Fedora example.

Fix released in 2.2.0.

[kleini]

The fix works for me.

Nice @kleini! Thanks for the feedback 😉
