SPOF server need not apply. Wait...you said servers. I say SO? Done
properly, the downtime for the upgrade would be minimal. Just a reboot.
Just the same amount of downtime you get when the thing crashes not if
not less considering that you first have to discover that it is down.

Ah, the wonderful perl/php dependency problem. Like I said, depends on
the requirements. There was a time when my mail servers which had no
perl/php dependency would be running the latest Fedora Core while
systems belonging to others would be running RH7.3...long after security
updates for RH7.3 were stopped.

Like I said, it depends on how you go about doing it.
