I think x86-defconfig should be usable by itself - not just via the somewhat obscure combination of: make defconfig make kvm_guest.config right? > > - Enable the cgroup features most distros rely on > > I've not yet had defconfig+kvm_guest.config fail to boot on debian > images (I occasionally grab one here: > https://cloud.debian.org/images/cloud/sid/daily/latest/ ) Systemd is rather negative about missing cgroup features - at a point it used to insert 30(?) seconds delays during bootup warning about missing cgroups support, etc. Also the main Debian derived distros (Ubuntu, etc.) plus Debian itself has most of cgroups enabled - so why should we test something that very few users are using?
