Hi folks,
AFAICS I have to list all containers to be started at boot
time in /etc/lxc/auto using symlinks pointing to the
config files. Problem: /etc is a local file system.
For a HA solution you usually have some kind of "network"
device/filesystem providing the resources to manage, e.g.
a DRBD
Those go through commands.c and are already mutex'ed that way.
Also remove a unmatched container_disk_unlock in lxcapi_create.
Since is_stopped uses getstate which is no longer locked, rename
it to drop the _locked suffix.
And convert save_config to taking the disk lock. This way the
save_ and

Make lxc_cmd_console() return the fd from the socket connection to
the caller.

Hi folks,
If its not too late for a suggestion:
lxc-stop could provide an option -A to shutdown/stop all
containers, independent from their autostart flag. Worst

the config files cannot be read anymore.
For my own part, if I want to stop
