Mergemaster doesn't do anything of the sort. It never takes action on 
any file or directory on the system unless the user tells it to.

When you say "it was all placed properly," what do you mean by that?

The good news is that if you actually followed the instructions in 
UPDATING you should have a copy of your old settings in /etc/namedb.bak. 
And of course, the mergemaster man page counsels you to make good 
backups before running it.

In order to debug this we'll need more information:

1. How do you usually invoke mergemaster?
2. Do you have a .mergemasterrc file?
3. Do you run a MM_PRE_COMPARE_SCRIPT?
4. Do you have any *_BIND_* options in /etc/make.conf?
5. Output of 'ls -la /etc/namedb /var/named/etc/namedb'

Hope this helps,

Doug
