glad that we found the problem. you see, this is the file that 'freebsd'
reads.

everything under /etc/default/ is a file that 'you' read. in general, you
don't want to make changes to these files (especially deleting them),
because they provide a documented list of the options available to you.
without them, you lose some visibility to your options.
these files can be reinstalled through the installworld/mergemaster
process, so it isn't the end of the world if you mess them up a little.
