How will it talk w/ the out side world? w/o random, No sshd, no https... providing randomness is a core component of a modern OS... If you're really going for small embeded, you don't want FreeBSD, or if you do, you're willing to do the work to manually rip a lot more out of the standard kernel than just the random driver... My stripped down i386 kernel is still over 6MB in size... > > I'm fine w/ making the various random mixers options, but the core > > random infrastructure and /dev/u?random should be standard now??? > > There is some compulsory infrastructure; this gets you the ???dummy??? > driver which just blocks and never delivers anything. Plus, you'd need to turn off the entropy boot script among other things... If you can demonstrate a usable system w/o much modifications that runs w/ the dummy interface, or no boot random, that I'll drop my suggestion... I'll try removing random tomorrow and see what breaks... -- John-Mark Gurney Voice: +1 415 225 5579 "All that I will do, has been done, All that I have, has not."
