NFS Server share /var/cache/yum?

[Frank Murphy]

Trying to replace an NAS with a PC.

Figured I'd check before creating
Having looked at:
https://fedoraproject.org/wiki/Administration_Guide_Draft/NFS?rd=Docs/Drafts/AGBeta/NFS

How can I share on the NFS server /var/cache/yum. 
so it will be available as a local(nfs) cache 
to all fedora boxes\vm's
as root shares are discouraged.

Server will  have the following hd for shares /sdc 1tb raid1
(Hope I explained it clear enough, a problem of mine)
