Why do people always assume that the only alternative to their clever
plan is some horrible activity? People who run clusters that aren't
"full SSI" clusters have means of dealing with this that are better
than what you describe.

I've especially noticed this with folks who promote using a single
root disk. I have clusters with 500+ root disks, and I assure you that
I have a suite of simple tools which keep them synchronized. Yet the
single rootdisk folks will tell you, "then you have the difficult
administrative task of..." and assume that anyone not doing it their
way has no tools...
