name   The name of the boot configuration to restore

       -h,--help
              Show a brief help page for the command.

       --no-backup
              Don't take an automatic backup of the current boot configuration if one doesn't exist

          pibootctl load [-h] [--no-backup] name

       The  load  command  is  used  to  replace  the  current  boot  configuration  with one previously stored.
       Effectively this simply unpacks the PKZIP <https://en.wikipedia.org/wiki/Zip_(file_format)> of the stored
       boot configuration into the boot partition, overwriting existing files.

       If the current boot configuration has not been stored (with the save  command),  an  automatically  named
       backup will be saved first:

          $ sudo pibootctl save default
          $ sudo pibootctl set video.hdmi0.group=1 video.hdmi0.mode=4
          $ sudo pibootctl load default
          Backed up current configuration in backup-20200310-095646

       This can be avoided with the --no-backup option.

       WARNING:
          The  command  is written to guarantee that no files will ever be left half-written (files are unpacked
          to a temporary filename then atomically moved into  their  final  location  overwriting  any  existing
          file).

          However,  the  utility cannot guarantee that in the event of an error, the configuration as a whole is
          not half-written (i.e. that one or more files failed to unpack). In  other  words,  in  the  event  of
          failure you cannot assume that the boot configuration is consistent.
