Right, so if you run into a situation where you need to run an old 
kernel-0.99, you'd protect it
with /etc/yum/protected.d/kernel-0.99.conf , assuming that yum allows 
specifying package version as well as the name.

By the way, currently the protected list seems to be  'yum, systemd and 
running kernel'. I don't have a system to try it on, so I just hope that 
one can't delete their dependencies either (glibc? what else?). I think 
you can still brick the system with careless yum erases: for instance, 
deleting grub/.

/That's why I like the approach of explicitly protecting against removal 
via .conf files---even though I don't see how to preserve the protection 
of the currently running kernel in this scheme.
