[arch-general] How to cache pacman mirror for LAN

I use a central server for simply caching with NFS (as in the wiki
basicly) for five machines at home. And it works great and not having
to add other packages just feels more simple in my imho. Was unaware
about not being able to use the cache simultaneously though and has
never been an issue for me. Will have to check that out, thanks for
the info! If you were to write a script for that maybe it could be
handy to put in the wiki?
