Say I have installed mypkg-1.2.3-4567.noarch.rpm from some yum repo.

  1. Is it valid for the rpm publisher to re-publish mypkg with the same version and release and just run createrepo --update? Is it recommended?
  2. If #1 is allowed, will yum upgrade my installation of mypkg if I run yum install mypkg again?

No, the rpm publisher has to increase the release number each time the rpm changes. yum update mypkg or yum install mypkg will have no effect if a package with the same name-version-release is already installed.

thank you. I searched but could not find this assertion in the yum man page or other official documentation. Could you please point me to something official that says this? – ottodidakt Apr 6 '13 at 6:41
