Note that even updates can bite you if dnf will always be removing the 
oldest kernel, even if that is the one you are running. There may be kernel 
or dracut problems keeping the newer installed kernels from being usable 
on a particular system. Also if the running kernel is removed, you won't be 
able to load any modules that are already loaded.
