[atomic] New mirror and new rawhide installer ISO available

[Colin Walters <walters verbum org>]

Hi,

First, Fedora Infrastructure has provided some scratch space in the
"alt" mirror.  Among other things, this has SSL, which fixes a major gap
in update security.

You should be able to switch running systems to:

https://dl.fedoraproject.org/pub/alt/fedora-atomic/repo

Edit /etc/ostree/remotes.d/fedora-atomic.repo and replace the url= value
with that.

People have also complained to me about the download speed - this should
be better, though it's not (to my knowledge) globally mirrored.

Second, I've uploaded a new installer ISO:

http://dl.fedoraproject.org/pub/alt/fedora-atomic/testing/rawhide/installer/201407/

There are two known major bugs with this:

- It will crash if you boot with < 1GiB of RAM, because of a kernel bug
with the new zRAM that landed in Anaconda[1].  You can work around this
with (strictly) greater than 1GiB of RAM, or by adding "inst.zram=0" to
the kernel command line.

- cloud-init is enabled by default; this will be fixed when
