Comment 3 for bug 1873303

Well, I do not _mix_ two separate issues, but I try to find synergies.
My hope was that if kernel/initrd is hosted in a proper way, it will not only help for people doing netboot installs (this ticket is mainly about this, as one can read in bug description), but maybe also for people using virt-install.
(I'm still thinking about a way to get virt-install, which is currently broken for focal, fixed again - the main conversation about this should be of course at LP 1872941.)
