How about something like this then (I was thinking making it a panic but
not sure). I think it's a good idea to give some kind of indication so
that there is at least some message when the user discovers that some
things specified on cmdline don't start/work.
Check if the user specified a too long kernel command line and warn
about it being truncated.
