That is an other topic which deserve a thread by itself. As Tizen we do not enforce a specific version of the Kernel but rather the provision for specific feature (e.g. Smack and SystemD boot). People maintaining the Kernel of each reference platform have the duty to provide a Kernel with the needed features. Getting it based on LTSi is certainly an interresting approach but not a requirement. > > There seems to be a lot missing before a suitable public port to ARM > can be done repeatedly in a manner consistent with production systems. > Is there a goal to add this type of support?

On Common Odroid should fix the issue by end of June. For IVI, it will be up to the reference platform providers to fix the issue of availability.
