One thing I have always done prior to running mergemaster is to set the console to 132 columns to make it easier to view long lines and to facilitate merging files. When I was running this new kernel (mismatched to the world) vidcontrol was completely broken, none of its commands would work. (anything I typed got met with something along the lines of "must be on virtual console, inappropriate ioctl for device". This problem went away after installing the world.) So I couldn't do anything with the default screen settings. I'd say it's a good example of the kinds of things that can break when you do it that way. So it appears each method has its pluses and minuses. (Maybe the ideal would be to test the new kernel then revert to the old to build the new system, but that would require a 2nd reboot) -- Philip J.
