The problem about having a builtin set is that they are still big enough to need tests and bugfixes and documentation and so on. If NetBSD already had a Busybox it might be a different matter. >> 3) deciding if we want applications themselves to handle backgrounding >> e.g. via daemon(), or limit backgrounding to rc scripts using &, and >> dealing with whatever problems arise as a result Things like dhcp need to background, so need to resolve quite early on. Something like crunchgen which creates an object file with a single entry point that executes a single binary would be a nice outcome. But it needs to deal with the memory allocation issues and globals. I fudged up a hacky version in a rumprun branch somewhere but got rather unhappy with it. Another option that just occured to me, as performance of this setup phase is not critical, might be to use a C interpreter eg https://code.google.com/p/picoc/ to run the NetBSD utilities... That then solves the namespacing issues, and allocation etc, obviously needs hooking into the rump syscalls. Then you just ship (compressed) source code in a config library. I might try prototyping this. >> Of course, this whole mail isn't really specific to Xen, and I'd >> eventually like to see things work the same way on all platforms. But >> we need at least one working platform as the first step ;) Some platforms might have extra options, but Xen looks quite a bit like many other environments I can think of. Userspace has similar issues which I ran into trying to get some benchmarking code working, when you dont use remote clients for performance reasons. > Of course I appreciate that some of the xenstore-based answers I give > above are perhaps less useful to other platforms, but perhaps they > have something equivalent ? Yes I think there is usually something roughly equivalent on most platforms, although some might be somewhat simpler.
