[ubuntu-za] automatic software updates

[Charl Wentzel]

Hi Guys

I just need a "kick" in the right direction here.

I'm developing software for Embedded Linux Devices.  I would like to
incorporate an automatic update system, similar to that which Ubuntu
does.  In fact I would like to use an Ubuntu Server as the update
server.

The snag is that the embedded devices are not Unbuntu based and have
very limited distribution.  So what ever I need to do on the embedded
devices I would probably have to write it myself or adapt and
cross-compile something existing. 

I don't want to re-invent the wheel.  Any ideas on what where I should
start my research?  Would using apt be a good option?

Regards
Charl
