There seem to be 3 main opinions in this area of cluster admin:
1) Install little or nothing on the nodes; reboot all the time
2) Heavy install on the nodes; re-image to ensure consistency
3) Heavy install on the nodes; other mechanism to ensure consistency
All of these have their pros and cons. You are correct that (2) needs
a fast re-image, since you're going to be doing it fairly frequently.
But (3) will only re-image once a year or two.
Some people in (2) reboot&reimage any time they change a single
rpm. That's a recipe for annoying your users, unless you have the
ability to do a rolling-reboot between jobs.
