Hi,

You asked a very good question. My answer is that linux embedded won't be
ready for prime time anything soon (in the next five year). There are
several reasons:

1. Linux kernel is a monolith architecture, like IOS right now. It comes in
one big chunk. Any changes means that you have to reboot the whole
system. That's not good.

2. Support for a whole range of microprocessors. Companies like RedHat sells
customer service, but they don't do heavy duty development. You need to
have a lot of heavy duty development in order to do the BSP (board
support packages) for a lot of different processors.

3. Suppose a company does develop a lot of support and also come up with a
good debugging environment. Do you think that company will still give
it out for free? I don't think so. The appeal of free linux is gone
once you start adding a lot of features.

I hope that answers your question. Let me know what you think. :-)

-Tawei
