Hi all :-)
This is my first post: I’m coming from debian/bsd world.

A question about repositories:

minimal installation (version 7) provides:

CentOS-Base.repo CentOS-CR.repo CentOS-Debuginfo.repo CentOS-fasttrack.repo CentOS-Sources.repo CentOS-Vault.repo

I known there are others repositories as:

RPMForge, EPEL, REMI, ATrpms, Webtatic (and maybe also others)

so, what kind of these repositories are?

Does they repositories substitute packages from main? Or only adding new packages?

thanks for advices and help!

Pol

  • Hi Pol,

    Welcome to CentOS and the mailing lsit.

    Start here for more information on 3rd party repositories:

    http://wiki.CentOS.org/AdditionalResources/Repositories

    Some may replace distro packages whereas others may have a policy not to replace distro packages (so only contain packages not in the distro). Some repositories split into channels where the main repo doesn’t contain distro packages but may have an “extras” channel that contains any packages that replace distro packages.

    Ultimately CentOS has little influence over what 3rd party repos do so the ecision / policies are down to each individual repo.

    The yum priorities plugin can be used to prevent 3rd party repositories from replacing distro packages:

    Hope that at least gets you started.
