lxc-update-config - update a legacy pre LXC 2.1 configuration file

lxc-update-config  detects  any  legacy configuration keys in the given config file and will replace them
       with the appropriate new configuration keys.

       lxc-update-config will first create a backup of the old config file in the same  directory  and  name  it
       config.backup  and  then  update  the original config file in place. In case the update fails to apply or
       leads to an invalid config file that cannot be used to start a container users can either compare  config
       with  config.backup  and  try to manually repair any the invalid configuration keys or simply rollback to
       the legacy configuration file by copying config.backup to config.

       Any failures for lxc-update-config to generate a useable config file are a bug and should be reported up‐
       stream.
