Hi, 

I don't think it's an issue, imgbase require additional parameter and the message is pretty straightforward, "too few arguments".

# imgbase 
usage: imgbase [-h] [--version] [--debug] [--experimental] [--stream STREAM]
               {base,layer,w,layout,check,motd,update,rollback} ...
"imgbase: error: too few arguments"

The tool will require the users to provide the subcommands like: 'base, layer, w, layout, check, motd, update or rollback' or use the optional arguments, like:

  -h, --help            show this help message and exit
  --version             show program's version number and exit
  --debug
  --experimental        Enable experimental functionality
  --stream STREAM

# imgbase 
usage: imgbase [-h] [--version] [--debug] [--experimental] [--stream STREAM]
               {base,layer,w,layout,check,motd,update,rollback} ...
imgbase: error: too few arguments

# echo $?
2 (Looks good, non success)

Finally, the "error" string came from argparse as one argument is required and it's non optional. Fell free to re-open the report in case you disagree.
