Fedup solves the live problem by performing the upgrade from a custom initramfs.

(I've been upgrading to rawhide for a few years by upgrading
rpm/yum/python then kernel/glibc then init/udev then everything else
but I haven't checked the Fedora wiki for a LONG time to see whether
this is still the approved method. They seem to be OTT because every
step seems to pull in more and more dependencies with every new Fedora
version!)
