I see. I moved the plugin to the dns subpackage. Is there any other
way besides restarting bind10 suite, how can I make cfgmgr reload all
plugins? Now if I install the DNS server part while bind10 suite is
running, the datasrc config plugin does not get loaded automatically.

I know there are these options, but we want to build the complete
bind10 suite and then just divide it into separate packages based
on the functionality.

Thanks.
