Sounds like tags and chaining, did something similar for upstart.
file { '/usr/lib/systemd/system/patcher-client.service':
notify => Service['patcher-client'],
tag => ['reload systemd'],
}
File <| tag == 'reload systemd' |> ~> Exec['systemctl daemon-reload']
Exec['systemctl daemon-reload'] -> Service <| |>
Originally (on centos6 where upstart+sysvinit is combined):
class upstart {
$upstartreload = '/sbin/initctl reload-configuration'
exec { $upstartreload:
refreshonly => true,
}
File <| tag == 'upstart' |> ~> Exec[$upstartreload]
Exec[$upstartreload] -> Service <| tag == 'upstart' |>
}
