Hi I have mirrored here on our site some nice yum repositeries from the internet and i have made some here from local software. it seems to work well but now i have a problem. There s different version of different in the different repositeries. how can i select the repositeries for different packages. for examples on a machine A i would like to install mozilla from repositery A but kernel from repositery B and openoffice from repositery C as all these packages are present in all repositeries. with apt i can play with preferences. Is there some kind of mechanism to do the same with yum? Thanks in advance
