This specification covers some of the daemon's behavior, such as reaction to given signals, crashes, ...
On every start, LXD checks that its directory structure exists. If it doesn't, it'll create the required directories, generate a keypair and initialize the database.
Once the daemon is ready for work, LXD will scan the instances table for any instance for which the stored power state differs from the current one. If an instance's power state was recorded as running and the instance isn't running, LXD will start it.
SIGINT, SIGQUIT, SIGTERM
For those signals, LXD assumes that it's being temporarily stopped and will be restarted at a later time to continue handling the instances.
The instances will keep running and LXD will close all connections and exit cleanly.
Indicates to LXD that the host is going down.
LXD will attempt a clean shutdown of all the instances. After 30s, it will kill any remaining instance.
power_state in the instances table is kept as it was so
that LXD after the host is done rebooting can restore the instances as
