I'm looking for a secure and flexible way of pushing custom updates to my users' Ubuntu 11.10 x64 machines.
I'm looking to push updates that will run scripts for adding new software, adjusting settings, etc etc etc..basically any changes I'd like to make to an Ubuntu machine, only on all of my users' systems. Of course I'd also like to control if/when these systems get the usual Ubuntu updates.
There's lots of info out there on setting up repos for updating a particular app; hoping someone could point me in the right direction for best methods of updating/reconfiguring Ubuntu systems and applications overall. Many thanks!
EDIT: Already aware of Landscape, and while very well suited for my needs it's out of our (non-existant) budget.
