Just an FYI: git over http on the repos being used for ARMv8 is not working quite as it should. I'm working with infrastructure admin folks to fix it.
In the meantime, the bootstrap scripts should be available from:
$ git clone git://fedorapeople.org/~ahs3/bootstrap.git
And the rootfs should be available from:
$ git clone git://fedorapeople.org/~ahs3/rootfs.git
Sorry to jumble things like this, but we should have it fixed soon, so this should only be for a couple of days.
