What is the rule of thumb for reboots after updates...

I'd say the rule of thumb is to do whatever works best for you, and that you'll likely get quite the variety of different responses. ;o)

Certainly if I update from 5.2 to 5.3 I reboot.

But if you update something like krb5 or pam does that require a reboot? Does the "fix" get automatically loaded and used or do you just do a reboot always?

If the kernel gets updated, obviously it goes without saying that you need to reboot for that. Also for 'init', or any of its dependencies.

Never for 'init'. Updates to 'init' will invoke "init q", which tells the running 'init' process to re-exec itself.
