You need to have all RPMs under some directory, to be able to create one repo from it, or yum won't be able to satisfy dependancies from the other CDs. You could perhaps trick it by ensuring that the headers directory (yum 2.0.x) or repodata directory (yum 2.1.x) is always available, and changing CDs when you don't have the right one mounted. Yum should download the packages it finds and then quit with an error, you can then mount the next CD, try again, ... ... eventually you have collected all needed rpms in /var/yum/cache, and the install will suceed. I don't recommend this method, it's not the point of yum. ;-) I have done it on Fedora by building a bootable DVD from the CDs, and creating the yum headers with yum-arch (yum 2.0.7.x, FC2) . For yum 2.1.x (FC3), you need to replace the yum-arch command with createrepo. (from the package of the same name) - I haven't got around to creating a yum-ified FC3 DVD yet. There are instuctions to create one DVD from RedHat / Fedora CDs on http://www.redhat.com/archives/fedora-devel-list/2003-October/msg00736.html, and a script at ftp://people.redhat.com/ckloiber/mkdvdiso.sh, but it must work similarly for YellowDog if you copy all the CDs to the correct directories, and you don't need to make it bootable if you don't burn it. I just modified the script (see below), but I usually edit it to only one step at a time, just to be carefull, and I mount and check the iso-image before burning it. I mount the image in my /etc/fstab and use it via a symlink as one of my local yum repositories, to avoid downloading rpms which I already have when yum needs to satisfy dependancies which haven't been updated since the original distribution. You can achieve exactly the same thing by copying the rpms from all the CDs to a hard disk directory and yum-ifying that, then add accessing it using a http / FTP / File url, depending on what you have running. The file URL only works locally or perhaps NFS / Samba / etc. - I use ftp (vsftpd).
