Hi, it seems to me that in postinst, instead of
if $do_systemd then systemctl start pmcd.service >/dev/null systemctl start pmlogger.service >/dev/null elif which invoke-rc.d >/dev/null 2>&1 then invoke-rc.d pmcd start invoke-rc.d pmlogger start else /etc/init.d/pmcd start /etc/init.d/pmlogger start fi You could just do service pmcd start service pmlogger start Additionally, I think a case can be made for ignoring failures to start these services in postinst. If the package fails to configure, that'll break unattended-upgrades which will then also not install security updates. AndrĂ¡s -- A hangover: the wrath of grapes.
