Cold restart vs hot restart is one thing, but I am more concerning about one node in system and another node in sysinit call while they are in the same cluster and SM needs to manage those different nodes still.

I like the idea, keep the current system working as it is and do not interfere with functionality in order to enable another OS has been part of our goals. The plugin solution is a great idea.  The testing part is naturally, the more features we have / os we run the more testing it is needed.

Does anyone one on the community think that this change need a spec?

Thoughts from other OSs ( Debian / Yocto )
