AArch64 Bootstrap Stage4 Notes
A copy of the current stage4 rootfs can be found at http://fedorapeople.org/groups/armv8/stage4-rootfs.tar.xz. It is a fairly minimal root with enough in place to build packages with mock. Of course, a yum repository is also needed to feed the mock chroot. An initial repo based on stage3 packages can be found at http://fedorapeople.org/groups/armv8/stage4-repo.tar.xz. This repo is temporary and a live repo available over the network will be coming soon. For now, the mock and yum configs in the rootfs expect the repo to be mounted locally at /stage4-repo.
Booting The Rootfs
The stage4 root will boot using systemd as the default init process. We have found some performance issues with systemd on the model. This hasn't been fully investigated yet. To avoid wasting simulator cycles while building, the stage4 root also includes a means to boot with busybox as the init process. To do so, pass
