[pve-devel] [PATCH] Revert "PVE:Daemon start/restart with systemd"

[Emmanuel Kasper]

This reverts commit a526ab1cfc6adda11dd4830501b1eb8a14b2bf6d.

This commit has two problems:
 * it breaks starting in debug mode, as calling systemctl
 do not pass the -debug flag
 * it has strange default, as no unix daemon would start/
 stop itself calling the init system in the background

 Reverting this patch do not change the way the services
 are started / stopped / reloaded via the API as API calls
 translate to PVE::Tools::run_command(['systemctl', $cmd, $service]);
