It has the ability to schedule arbitrary code to be run AFTER teh new kernel has booted (so that the arbitrary code is running on the same systemit was compiled on) but before the actual application starts, but that's too late for changing the bootblocks. > > Interjet owners may upgrade their Whistleware(TM) at any time or > > they may decide to NOT upgrade it. > > Sure. > > > We can't MANDATE that they > > upgrade.

If you can install > and run software, then you can upgrade the bootblocks. yes but that would require 2 upgrades in a row.. one to load the new bootblocks to install them, and one to load and run the ELF based system. I'm not saying it's impossible but it flies in the face of "don't annoy the custommer". In the end we may end up with a double upgrade, but that is a pain because we only retain 1 backwards revision on the machine so the custommer could not revert to the old system they were running after the 2nd upgrade should things go wrong with it. > > If it's not possible, then I guess Whistle screwed itself here by not > thinking ahead, didn't it? I admit we didn't consider in 1996 about replacing the bootblocks on the fly, but I think you'd be pleasantly surprised by just about every other facet ot the upgrades etc. :-) > > > Of course it's not FreeBSD's job to make things easy for me, > > so that's ok, but I think that since Linux uses /Linux, and > > NetBSD uses /NetBSD and OpenBSD uses (I think) /OpenBSD, > > using /FreeBSD would make us more 'in line' with the others, > > and also backwards compatible with systems that are set up > > with old bootblocks. > > Didn't your mother tell you that 'if all your friends jumped off a > bridge, should you do it also' argument growing up. :-) >> > > No matter what FreeBSD does, we will probably have a 3rd stage > > loader called "kernel".

You may be right. That's a decision for 'marketting'. Remember that this is an 'appliance' that should "just work" so the custommer expectation is that they shouldn't have to do very much.... Mind you, a 'boundary' release between major branches of the code does have some advantages. > > Nate To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe cvs-all" in the body of the message
