Dependency on csh

[visualblind]

Not sure exactly where yet, but the service "emby-server" fails to start automatically once the root users default shell is changed to something other than defaults (I used bash). Not a big problem, although I think we'd agree there shouldn't be any specific shell dependencies unless absolutely necessary. I'll mess with it again when I can.
BTW, great script, one of the most useful I've seen for recent versions.
