So, first up, thanks for agreeing to do this. It sounds from your mail like you're already pretty well aware of the usual pitfalls with this kind of work, and I don't really have much to add that's QEMU specific that nobody else has said already. One question I do have is about the other BSDs: bsd-user at least in theory is supposed to support freebsd, netbsd and openbsd. Your patchsets should fix freebsd, but do you know what the status is of netbsd and openbsd? Upstream we do compiletest but no runtime testing; I think last time I tried it they didn't work very well, but it would be worth checking with the other BSDs downstream to see if they're using bsd-user and to make sure we don't break anything that is currently working for netbsd/openbsd... thanks -- PMM
