How to use YUM to localy update FC6

[Erik Grootjans]

Hoi,

I have a small network with 3 computers.
I want to download the updates only once - using yum or some other
program.
Yum has to update the local computer, but must not delete the updates

After that i want to use the same packagefiles to update the other 2
computers
1) How do i configure yum that it does NOT delete the files, (or let it
copy them to an other directory)
2) How do i configure yum on the other computers to look localy

Thanks

Erik
