yum repos question

[Phil Savoie]

Hello everyone,

This question is such a simple, obvious question, but I can't find the
answer anywhere.

When you have several yum repos files in /etc/yum.repos.d and you decide
to use yum to install some software, if that software can be found in
several of the repos, which repo gets priority?

There are three answers I have seen:

1) use a plugin--- yum-pugin-priorities       However, several sites
have warned against the idea of put a priority level on the different
repositories.
2) use the "--disable repo" to disable any repos when installing (this
assumes you know which repos have the duplicate software!)
3)   from the man page:  (but this only applies to when you have more
than one baseurl in a stanza, NOT two completely different repositories
that both have that software)
"failovermethod Either 'roundrobin' or 'priority'.  under each repo
stanze 'roundrobin' randomly selects a URL out of the list of URLs to
start with and proceeds through each of them as it encounters a failure
contacting the host.
'priority' starts from the first baseurl listed and reads through them
sequentially.
failovermethod defaults to 'roundrobin' if not specified."


Any help is appreciated!

Thank you.

Phil
