Most OS's out there are unsuitable for making appliances, which this seems aimed at.

Right now your choices are a Realtime OS or Linux. Realtime OS don't support making GUIs and Linux has a lot of foot-guns.

Normally, updates to an appliance are one binary blob, this looks to support all of the various pieces having their own blob, and allow the OS to be updated independently from the application binaries, so security updates can happen without the appliance vendor needing to do anything.
