LXC 1.0.6 release announcement¶

2014年9月24日
This is the sixth bugfix release for the LXC 1.0 series.

To make supporting both LXC 1.0 and the future LXC 1.1 easier, this version introduces the -F argument to lxc-start.
This argument is a no-op as lxc-start is already running in the foreground by default, but as that behavior will change in LXC 1.1,
introducing -F in 1.0 too allows for writing script which will work consistently on upgrades.
