P2 Update Manager Not Allowing Update without restart

I am noticing that if my application requires Declarative Services bundle (in my case, I am using org.eclipse.equinox.p2.ds),. And, if my run launch configuration requires ds and the org.eclipse.core.runtime to be started at startup, I am forced to restart after any update to see the effect of the update.

update:
I stumbled on this link: which appears to address my problem. Apparently, if you configure your own start settings, then you must also explicitly setthe following start values for p2 to work properly:

Bundle	Start Level	Auto-Start
org.eclipse.equinox.simpleconfigurator	1	true
org.eclipse.equinox.common	2	true
org.eclipse.update.configurator	4 (default)	true
org.eclipse.core.runtime	4 (default)	true
org.eclipse.equinox.ds	1	true
