I am trying to keep my Centos 4 system at home up to date, and add some software, but I am having a hard time because I am on dialup. I have high speed access at work, and can download packages there, but am having a hard time getting past the dependency loop I find myself in with yum. What I need is way to tell yum "I want to install foo" and have yum tell me "here is the list of packages you need to get at work tomorrow in order to install foo" What I have done so far is to create some "local unpopulated mirrors" on my local hard drive. The contain the directory structure for a mirror, but are basically empty. I have written a script that uses rsync to update the files in the repodata directory over my dialup, and that works well. yum looks at these local repo drives for all it's information. I can do things like "yum list all foo" and "yum deplist foo" and "yum resolvedep foo", and they all work fine, but none of them gives me the information I need. I have tried deplist, but it lists global dependencies. Even for packages that are already installed on my machine, it gives me a half a page of dependency information. Abundant information, but totally useless for my purposes. If I do an "yum install foo", yum exits because it cannot download the headers. I assume this is related to the "ToDo" and wish-list items about not downloading headers. If I could get yum to proceed through the install until it gets to the y/N question, it would have told me the files it was going to need, and I could write a script to extract those names. I have noticed that when I run "yum resolvedep foo" there is a number in front of the file name it returns, but I have found no documentation on what that number means. Does a 0 mean that the file is already installed? If so, I might be able to filter the "dependency:" output of deplist to figure out what I already have, and what I need to download. If someone can point me to a simple way to get that file list of unresolved dependencies, I would be very grateful. Ted Miller
