If you set up a local repo (i.e. a repo on your some other machine on your LAN) then you can give it a higher priority than repos farther afield. > I see that there is a yum-downloadonly package, > which I just installed. > This adds an option --downloadonly. > > I assume that you can then later run "yum update", > and it will install or update the packages that were downloaded, > as well as any other new ones. > > If that is so, then it seems to imply that yum looks first > in /var/cache/yum/ to see if required packages are already downloaded. > If it finds them there then it uses them; > otherwise it downloads them from a remote repository. It doesn't look just at the package files but at the package database, but essentially that's what's happening. > That being so, my question is: why not allow yum to look at > what yum has saved on another computer? Because yum only knows how to talk to repos, which have a specific layout (i.e. they aren't simply a yum cache directory). If the other computer doesn't have its stuff organized as a repo, how is yum going to know what's there? Note that it also has to run a transport demon that yum understands, i.e. http or ftp. > I notice that after installing the yum-downloadonly package, > there is another new option --downloaddir=DLDIR > which seems to allow RPMs (and other files in /var/cache/yum/ ?) > to be installed in a specified directory. > > It's not clear to me if yum will remember this new directory > if I use both these options --downloadonly and --downloaddir=OLDIR ? > Or will I have to specify --downloaddir again when updating? > > Is all this a possible way of saving RPMs on a /common directory > served by NFS? What you mean is to have your yum cache directory mounted from an NFS server? In principle yes, but I'm not sure about locking issues. > I suspect I may have misunderstood the basics of yum ...
