you actually removed all running kernels, it would be the _only_ Fedora
option (and the only option at all on a system without multiple OSes
installed, so booted by default).
Not going to happen here, I use the nohostonly and norescue options to
disable that nonsense "feature".
So removing all kernels will not only make the system unbootable for the
lack of a kernel, but also leave grub.cfg with no kernel listed at all, and
thus grubby without a template to write new kernel entries from, ergo I
would not only have to reinstall the kernel from a rescue environment, but
also manually fix grub.cfg! (Maybe grub2-mkconfig would be sufficient for
that purpose these days though. In GRUB 1 days, it meant having to write the
entry by hand!)
