[pve-devel] [PATCH lxc+container] fix pvedaemon restart issues

[Wolfgang Bumiller]

As explained in the pve-container patch's cover letter:

  Until now the lxc-start process was sort of a danglign
  process in the pvedaemon.service cgroup when a container was
  started from the web UI causing long stalls when trying to
  restart pvedaemon and potential container kills. (Mostly
  problematic when issuing package upgrades).
  We now start containers via the lxc@ service file giving
  them their own service cgroup.

  The downside is that we'll have to patch the lxc@ service
  file in the lxc package to Type=forking without the -F
  option otherwise all of the the containers' console outputs
  will end up in the logs...
