the lustre manual search page does not get any hits on 'writeconf'

The manual page (from the debian packages) for 'tunefs.lustre(8)', does
however document --writeconf

Somone asked me why I work on this free (http://www.gnu.org/philosophy/)
software stuff and not get a real job. Charles Shultz had the best answer:

"Why do musicians compose symphonies and poets write poems? They do it
because life wouldn't have any meaning for them if they didn't. That's why
I draw cartoons. It's my life." -- Charles Shultz
