You cannot know what the user wants.

I disagree. See my the example in my previous message why they are
evil.

It's not up to you to decide that he should not touch it or  that  he
cannot  use it. He can do *everything* on this system. Including very
stupid things, but maybe also a few pretty clever things.


This is why I love U-Boot and always feel frustrated when I  have  to
deal with things like a x86 BIOS (ah, great, it offers serial console
access, so I can do remote administration easily; now what - the RAID
controller needs ALT + F1 ... on the serial line... grrrrghhh).

Best regards,
