[lxc-users] How to cancel lxc-autostart

[Łukasz Górski]

Could you perhaps clarify when exactly do you want this command to be
invoked? Before the reboot or after? If after, perhaps I am mistaken, but
it doesn't seem to make any sense whatsoever. I suppose you'd need to run
it in a specific timeframe before the containers are started - how much
time it takes from the moment you get a working shell after the reboot to
the point when container booting process starts? If you want to run it
before the reboot, then I guess some shell scripting most likely would do
to disable autostart and the re-enable it back again after reboot.
