sysupdate provides a lot of incredibly useful primitives for doing system updates, but it is still mostly designed around old-school SHA256SUMS distribution and static transfer definitions. However, the need to have more autonomous systems for updating systems and adding components became quite clear when we started developing such systems at Amutable. This approach also dove-tailed nicely into developing an autonomous provisioning system using the same underlying mechanism.
This talk will contain a detailed description of the architecture we came up with, along with some of the caveats that such an architecture has with generic distributions.
