The ONLY data corruption that I saw when my laptop died was *ALL* of
the +CONTENTS files going away.  It seems to have died during the
updating of the meta-data for the dvdauthor port.  Why all the files
of unreleated packages would disapper is a mystery to me, unless
mergemaster, or one of the pkg tools, deleted them all, and then
wanted to rewrite them and I got screwed between these two steps.

I think you're thinking of portmaster, mergemaster doesn't touch ports stuff. What portmaster does when it updates +CONTENTS files is to update a temp copy first, then move the updated file into place after it's done. Not sure what portupgrade does.

In terms of easily recreating them, I can't think of a way to do that reliably other than to build the ports again. portmaster relies heavily on the data in +CONTENTS, and it couldn't even rebuild your ports in place without them since it wouldn't be able to find the ORIGIN.

What you could do with portmaster is to pick a high level leaf port with a lot of dependencies (something like firefox) and do 'portmaster -aft /usr/ports/www/firefox' (make sure you specify the directory in /usr/ports, not the pkg directory).

hth,
