(apologies for what will be some upcoming trivial questions, but i'm jumping back into centos after years and years of living with fedora, so i'm feeling fairly comfortable, just the occasional centos-specific question.) is the wiki repos page fairly up to date? https://wiki.centos.org/AdditionalResources/Repositories i ask since i note that its last edit was 2017-06-25, and things might have changed in the last several months. rday
