One area I would check is /etc/master.passwd and groups. It would be 
really interesting for you if your user accounts all disappeared. I 
also won't let mergemaster touch my hosts and printcap files.

I would also go to the trouble of tee'ing the makes and create logs of 
the makes and installs. Since you are going on, you want to know what 
you have done. What I typically do is

make     buildworld 2>&1 | tee /var/log/build/bworld-`date 
"+%Y%m%d-%H%M"`.log

Sorry about the wrap but I have kmail set at col 72. I have relatively 
large /var and /tmp and just added ../build to /var/log. The date 
required minutes in order to be unique. I also log all of my cvsups.
