They essentially have a server that has no admin right now...so they're looking for somebody who can take it over and keep things up-to-date.
One problem, it's RedHat. As in, Redhat 7. Which, as many people know, is not easily upgradeable. And, it's had no administrator for several months, so it's almost certainly very much out of date (I mean, aside from the fact that it's Redhat 7).
Assuming I get the job, this should prove to be a challenge.
Anyway, class time.
