You can set the versionlock file to be somewhere remote, eg locklist=http://my.main.server.com/versionlock/distro/$releasever or similar. Then you just control that one file, all yum update/install operations will use the versions specified there no matter what other versions are available. > Also, now that the download-only option has been moved out of yum > itself, how do you tell it to pre-fetch the packages you are going to > need (either for this or a normal 'update'), so as to be able to plan > the timing of the actual package installation/updates in a way not tied > to internet bandwidth or health of remote repositories? One way to do "download only" with current yum itself is to set tsflags=test in yum.conf, that way it'll just perform a transaction test but not actually do anything to the system. Or you can write a five-line plugin to make it stop once download completes. - Panu -
