[lxc-devel] [PATCH 2/2] Support files for systemd on Fedora.

[Serge Hallyn]

Quoting Michael H. Warfield (mhw at WittsEnd.com):
> Added a file "lxc.service" for a systemd service file.
> 
> Added a file "lxc-devsetup" to setup /dev/ on startup to support autodev
> in containers.
> 
> Service file references lxc-devsetup as an ExecStartPre command.  The
> lxc-devsetup script is not dependent on systemd or Fedora and can
> be used at bootup on any system.
> 
> Modified lxc.spec.in to install the two new files on Fedora.  The systemd
> specific code in the lxc.spec file may need some review and conditionalize
> for systemd on non-systemd rpm-based systems.

Will systemd care that the lxc-startup specified in ExecStart and
ExecStop doesn't exist?
