Ah, this was rawhide done from a boot.iso image.

True, I know I could just do a text mode install.

I'm not sure that's the case any more though. There used to be a stage1
and a stage2 image for Anaconda, but now I think it's all a live image
within that 100+ MB boot.iso file, without a separate download stage2.
Perhaps I'll do another install later and switch to the console (it's
cool that there's a usable shell early on now too) to check tmpfs.
