Yeah, I filed a bug report against the documentation some time ago. https://bugzilla.redhat.com/show_bug.cgi?id=1410948 ...though bugzilla is currently down. > Is there a way to install such hosts w/o having to temporarily raise > the available memory? None that I'm aware of, as of 7.3. If you have a 7.2 install tree, you can boot the older installer and then update the installed system. Seems easier to boost the memory, typically.
