NAME

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

SYNOPSIS

       lxc-update-config {-c config}

DESCRIPTION

       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 upstream.

OPTIONS

       -c, --config
              Path to the configuration file to update.
