Ah, I wasn't aware of the startup/shutdown hook scripts either, that'll be a
perfect place to add/remove the symbolic link in /etc/lxc/auto
Do you know if lxc.hook.post-stop is run even if you power off from within
the container with shutdown -P now?
Also, can I define multiple post-stop hooks? For example, if I wanted to run
2 commands but didnt want to distribute a custom script to all my hosts?
The Ubuntu docs dont call that point out specifically.
Thanks much,
David

containers after power failure
Dear David,
this will require to persist the current "power state" of a container by
some kind of marker. A tricky way is to mark some container-related file,
e.g. to ("miss"-) use the sticky bit of the containers lxc configuration
file or to put some marker file into the containers rootfs.
This will allow to write an init script that will scan for such a marker and
(re)start the corresponding container. Using LXC's startup/shutdown hook
scripts, you may event set such a marker automagical and especially to
remove it on a regular shutdown.
