The last answer here

https://ask.fedoraproject.org/en/question/72775/will-dnf-remove-kernel-underneath-it-self/

Seems to imply that exclude will accept a full version name. So

exclude=kernel-4.2.5-300.fc23.x86_64

might well do the trick.

I'll have a play with that tonight.

Also, a friend on irc has suggested that I look at the versionlock plugin.

Thanks,

Dave...
