[RaspPi] Snappy Ubuntu Core on Raspberry Pi 2

Wed, 04 Mar 2015 12:55:09 +0000

Well, I finally got my Raspberry Pi 2 and just could not hold back and wanted to test Snappy Ubuntu Core and give a little introduction and how that thing works.

Ok, but short into: What is Snappy Ubuntu Core?
Well it is meant to be a secure operating system for embedded applications.
It is based on an transactional system-management and can even rollback upgrades of the system core.
There are three kinds of Snappy Ubuntu Core Components:
Snappy Ubuntu Core itself (Core), Frameworks and Apps.
Frameworks can access the Core in certain ways and thus need to be reviewed by the Ubuntu Team.
Apps are completly isolated from each other and have limited access to the system, therefore they don’t need special security profiles or reviews, which makes publishing easier.
Ok, and everything is controlled via the command “snappy”.

Internet of Things is the latest buzzword beeing used in the media and a new sector for the entire electronics industry.

This paper examines the current problems with an normal homebased “Internet of Things” system and how the information technology industry is more concerned with profit versus user security. Ultimately, we need to decide for ourselves whether we want to continue using these types of technology.
