NAME         top

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

SYNOPSIS         top

       lxc-update-config {-c config}

DESCRIPTION         top

       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  up‐
       date  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  con‐
       fig.backup  and  try to manually repair any the invalid configura‐
       tion 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         top

              Path to the configuration file to update.
