I don't like to get a shell at users as he might be an end user and
don't know what to do so I'd prefer to have a proper error message and
support the shell as fallback depending on a boot param or so (so it
can be used during development).

Another issue is the amount of time waiting ... I have hardware that
takes up to 8s to be ready so 3s is too short and the amount of time.
The time to wait should be configurable by bootparam too (and
documented in commitlog).

Regards,
