I am using a custom Linux distribution.
It is minimal.
It uses yum but has very small amount of packages in its official yum repo.
yum search does not find any matching records. So far as I know, no additional repos are available.
I found RPM Find: http://www.rpm-find.net/linux/RPM/, but it seems that if I want to do it this way, I will have to download all packages according to each other's dependency list one by one. It might be okay for a small piece of software, but for X desktop, people say it could results in 100+ packages that needed to be installed. Obviously I do not want to download these packages manually.
Is there any public yum repo that I can add to yum so it can install X desktop from it, or is there a faster way to get all dependencies automatically?
