Very much so. Almost anywhere I've ever worked, no management would
*allow* a production server that was this far out of date.

Further, if it were up to me, there's *no* way I'd allow fedora in a
production environment. It's a development line; I'd expect management to
demand either RHEL or CentOS, which are stable production-quality lines.
They don't have the latestgreatestmostwonderfulness... but when that moves
into these distros, they're not going to break when you look at them
wrong.

So you're going to upgrate to FC3, 4 and 5 before going to CentOS?

I agree. If someone handed me a mess like that, I'd be building a new
production server, test it, and get that out of production as fast as I
possibly could. If you, or whoever, got another job, or were hit by a car
tomorrow, whoever had to pick it up would be SOL, and it'd probably crash
before they figured out what had been done. It would take you as much time
to document as to
     a) build a new, stable CentOS 5 or 6 box
     b) install everything required on it
     c) recompile anything in-house that needed to be rebuilt
     d) test it all, and put it into production,

and I guarantee that you'd miss documenting something vital.

A *lot*.
