Right.

No, it's not. But I have doubts whether bootm is a good place for it.
Maybe we should rather go for new generic command, something like
'imrun' or similar. And maybe even, move standalone application
execution from bootm to a dedicated hook that'll be available from
'imrun'. This way, bootm would become strict OS booting command,
potentially also available from 'imrun' via a hook.

How that sounds?
