I'm not sure, I always set growisofs setuid root on all my machines,
because I'm too bored to use sudo just to burn some discs, and it works
fine:
ls -l /usr/local/bin/growisofs=20
-r-sr-sr-x 1 root wheel 63620 Jun 16 22:45 /usr/local/bin/growisofs*
$ growisofs --version
* growisofs by <appro@fy.chalmers.se>, version 7.0.1,
front-ending to mkisofs: mkisofs 2.01.01a05 (i386-unknown-freebsd6.2)
Must be something else.
