USAGE

       The diff command is used to display  the  differences  between  two  boot  configurations;
       either  two  stored  configurations  (if  two  names are supplied on the command line), or
       between the current boot configuration and a stored one (if one name is  supplied  on  the
       command line):

          $ sudo pibootctl save default
          $ sudo pibootctl set video.hdmi0.group=1 video.hdmi0.mode=4
          $ pibootctl diff default
          +-------------------+----------------+--------------------+
          | Name              | <Current>      | default            |
          |-------------------+----------------+--------------------|
          | video.hdmi0.group | 1 (CEA)        | 0 (auto from EDID) |
          | video.hdmi0.mode  | 4 (720p @60Hz) | 0 (auto from EDID) |
          +-------------------+----------------+--------------------+
          $ sudo pibootctl save 720p
          $ pibootctl diff default 720p
          +-------------------+--------------------+----------------+
          | Name              | default            | 720p           |
          |-------------------+--------------------+----------------|
          | video.hdmi0.group | 0 (auto from EDID) | 1 (CEA)        |
          | video.hdmi0.mode  | 0 (auto from EDID) | 4 (720p @60Hz) |
          +-------------------+--------------------+----------------+

       For  developers  wishing to build on top of pibootctl, options are provided to produce the
       output in JSON (--json), YAML (--yaml), and shell-friendly (--shell):

          $ pibootctl diff --json default 720p
          {"video.hdmi0.mode": {"right": 4, "left": 0}, "video.hdmi0.group":
          {"right": 1, "left": 0}}
