Strictly speaking we have check_workspace_recipe() for this. It could be that we should extend the message printed by that to be a bit more friendly and suggest devtool add/modify/upgrade first, but I'd like to be consistent.

We should already be handling this in devtool-source.bbclass, but I'm guessing the hardlinking you're adding bypasses that, so we likely need to handle that separately during devtool modify rather than here (preferably without duplicating code).

To be consistent with other subcommands and a bit more readable this should be something like:

    parser_menuconfig = subparsers.add_parser('menuconfig', help='Alter build-time configuration for a recipe', description='Launches the "make menuconfig" command (for recipes where do_menuconfig is available), allowing you to make changes to the build-time configuration. Creates a config fragment corresponding to changes made.', group='advanced') 
    parser_menuconfig.add_argument('recipename', help='Recipe to reconfigure')

Additionally, I would really like to see some oe-selftest tests for this along with the changes.

Cheers,
Paul
