Well, I've run into more weirdness .
yum update won't run because there's something called seamonkey-nss and 
seamonkey-nrps (can't recall exactly now, not at that terminal). Neither can 
be updated, neither can be removed, neither can even be found on the system. 
However... one or both seem to be dependant on fenced.

Anyone else come across this?
