So cells could be marked as boot-time-active or not, and those cells would 
get written out to CellServDB. Additionally, cells can be activated 
dynamically, but they wouldn't be started on next boot?

This seems reasonable. Would we use another file to track this? I don't 
like the thought of checking each cell to see if it has been activated, so 
I'd prefer the have the info written to a file.
