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!)
