Fetching the installer's root image must work using the same access protocols as are required for fetching package sources in currently active milestone. Installer must work correctly even if the remote location doesn't contain a full installable tree including package repository, but just the root image and files relevant to it.

It must be possible to install by booting the installation kernel
directly, including via PXE, and correctly specifying a remote source
for the installer itself, using whichever protocols are required to work
for package retrieval at the current phase (Alpha, Beta, Final). This
must work if the remote source is not a complete repository but contains
only the files necessary for the installer itself to run
I like the basic idea of the criterion. I'm still not really sold on
what phase we should be applying it to, though PXE and virt-install
together are obviously fairly good arguments for alpha or beta...
