You can use that to either autoinstall some files, or delete some from the temporary root tree (I'm not sure if the latter will work). If the problem is the output of diff, you might try using setting the nvironment variable DIFF_OPTIONS to something that is safe for your modems. If mergemaster does things that muck with that, setting DIFF_FLAG might change it's mind. <mike -- Mike Meyer <mwm@mired.org> http://www.mired.org/home/mwm/ Independent WWW/Perforce/FreeBSD/Unix consultant, email for more information.
