I believe Jacco used F18 to bootstrap the build. Not as easy as it
would have been with F19, but it worked out.

You can create the image yourself. Take a basic EL7 x86 system
(minimal install), grab the list of packages from that using:
rpm -qa | sed -e 's/-[0-9].*//' | sort -u > packages.list

You can then feed that to yum:
yum --installroot=/path/to/media `cat package.list`

Add a suitable boot loader configuration, kernel, initrd and
/lib/modules/ and you should be good to go.

It's not particularly newbie friendly, but it's not very
difficult, either.
