Things I've written or acquired to help manager Ubuntu
reindex_stable.sh- Create a local APT repository on CentOS, useful for releasing your own packages or packages you want to keep seperate from the upstream release packages.
Based on: http://troubleshootingrange.blogspot.com/2012/09/hosting-simple-apt-repository-on-centos.html
sync-ubuntu.sh- Wrapper arounddebmirrorto mirror only specific releases from upstream. Kind of a mess and work in progress, but usable.
