I am not involved with QEMU maintenance. I suggest that you contact Doug Goldstein for details.
As for systemd, why is it that the GNOME project feels that mandatory dependence on such features is necessary when the KDE project does not? The KDE project seems to have no trouble writing cross platform compatible code. The only instance in which KDE fails to be cross platform involves Network Manager, which is Linux specific. As far as I know, Network Manager is developed primarily by RedHat employees. They seem to only care about Linux (and quite possibly, only RedHat's version of it). This causes headaches for us because Gentoo encompasses more than just Linux. Unfortunately, our teams dedicated to non-Linux things lack the man power necessary to address that issue.
With that said, Gentoo has its own cross platform solution called OpenRC that runs on top of sysvinit. I do not think that we would be having this conversation had OpenRC been incorporated into Fedora instead of Upstart.
