Agreed...but I've always felt (IMHO) that configuration management
is the job of the operating system or an offline separately-bootable
diagnostic image. Yes, they're a pain, but for the frequency of their
use, I think they handle the job quite well.
My point is...ROMs should be simple, bulletproof, and as bug-free as
possible. Therefore, simplicity is called for. Non-ROM software is
much more easily updated, and as such, can afford to be more complex.
The flash approach (which I *really* like, by the way) that the Alpha
systems take is an interesting cross between the two.
