I'm not sure what you mean here. When KDB is enabled, it's built into
the kernel. There's no supporting userspace. We only enable it in the
- -debug flavor of the kernel, but I'm looking into why we don't build it
into all flavors and only enable it by default on the -debug flavor. KDB
will be invoked on panic, or when you hit the pause button on the
keyboard or control-a on a serial console.
