I'm not entirely sure how, but it was the existance of the 
/etc/sysconfig/comoonics-chroot file that was breaking things. I just 
looked through the new RPMs, and that's not where it came from. I can only 
guess that I created it to silence a warning, and then later removed it 
from /etc/comoonics file list. The configs got replaced by the new RPMs 
and put it back in, which is what broke it.

Instead of replacing the files in /etc/comoonics, perhaps it would 
be better to create them as file.rpmnew, to avoid clobbering an existing, 
good config.

Anyway, the new RPMs are good. They meet the "it works for me" approval.
:-)

Thanks again, guys.
