[Server-devel] Tying yum to a package "stream"?

[Martin Langhoff]

OLPC's XS ships a number of patched packages. The packages are
normally built with a different "stream" or "flavour" (they don't say
"f9" but "xs05") and sit in a special repository.

Is there a good way to ensure revisor/yum prefers the packages from
the xs stream or repo over the standard F9 release or update packages,
even if the f9 package is newer?

(In the APT/Debian world the closest parallel would be setting apt
preferences to have biased priorities -- aka Pin -- on a label or a
component.)

cheers,
