Hi Robbie,

it depends on how your root thread is set up.

If it holds remaining master capabilities to objects in the system, you need to make sure those are not destroyed, because deleting them would delete those objects.

If you don’t want to hand out these master caps and untyped caps to the rest of the system (often there are good reasons for that), you would usually leave them in an inert CNode that also has a capability to itself. That CNode could just be the root thread CNode.

You can then safely destroy the root thread, e.g. make it suspend itself. If nobody else has a capability to it, it can never run again.

Cheers,
Gerwin
