Available Commands:
activateifneeded Check if LXD should be started
help Help about any command
import Import existing containers
init Configure the LXD daemon
shutdown Tell LXD to shutdown all containers and exit
version Show the server version
waitready Wait for LXD to be ready to process requests
Flags:
-d, --debug Show all debug messages
--group The group of users that will be allowed to talk to LXD
-h, --help Print help
--logfile Path to the log file
--syslog Log to syslog
--trace Log tracing targets
-v, --verbose Show all information messages
--version Print version number
