apt-get / yum, temp files?

Do those programs keep a copy of packages on the HDD after installing them?

I want to start keeping them as I've always liked keeping all the packages I use on my server so they're handy for later installing, or if the owner pulls it off the web - I've had this happen a lot and my server was a savior - there are many old apps out there I still use since they're good but you can't get them online very easily.

I'd want to do this for both apt-get and yum since I use both redhat and debian based systems in my house. So would be neat if I can auto build my own local repository. How hard would this be? Do those just download .deb .rpm packages then install and download dependencies as needed from same source? or is there more to it then that?

The default install of yum on Fedora/Redhat keeps its cache at /var/cache/yum - you can check /etc/yum.conf for the location of your rpm cache, in case it differs.

That would be the easy way of keeping copies of things you have installed. If you want something more elaborate a google search for yum repository should yield a slew of information on how to create your on local repository.

APT keeps them in /var/cache/apt/archives but your distro might clean that up periodically as it can get pretty large. For older Debian packages there's also snapshot.debian.net which has most packages from Debian since 2005.
