freebsd-update - Automatic merge

[Peter Kirk]

Updating freebsd 7.2 to 8 and fan the following command 

freebsd-update upgrade -r 8.0-RELEASE

Everything goes through fine but then it gets to a point and its says 

The following file could not be merged automatically: /etc/amd.map
Press Enter to edit this file in vi and resolve the conflicts
manually...

It goes through hundreds of files, and it wants me to do the editing all
myself, is there not automatic way to do this or just a simple yes no
like mergemaster would ask?  This would take forever on our production
servers
