surprised I have not seen anyone mention the other two things which can conspire to cause reboot trouble (with the kernel) with long uptimes
- automatic updates by yum-updatesd
- small (only 3) installonly_limit
If you are not careful, the last known working kernel is gone when you go to reboot. :(
I usually am mindful of both of these settings.
I would seriously advise against using yum-updatesd on a server deployment. It will screw up at some point and that point will most likely be when you can't afford to have it screw up.
Having said that, yum-updatesd on a desktop is fine, and probably a good canary for the server updates (but I wouldn't have it go on a large desktop deployment).
