The Handbook has good documentation on using dvd+rw-tools as well as other
software, and I would second the recomendation that people take a look at it if
they want to burn CD's or DVD's.
You are welcome to hold the opinion that the documentation is complete, but:
13-sec% cd /usr/ports/sysutils/dvd+rw-tools && make extract > /dev/null
14-sec% grep luke work/dvd+rw-tools-5.21.4.10.8/growisofs.c
* - undocumented -use-the-force-luke flag to overwrite the media
* - extended syntax for -use-the-force-luke option, it's now possible
* to engage DVD-R[W] dummy mode by -use-the-force-luke=[tty,]dummy
* - complement -use-the-force-luke=dao[:size] to arrange for piping
* - implement -use-the-force-luke=seek:N -Z /dev/dvd=image to arrange
* -use-the-force-luke=seek:N it's easier to maintain "tar-formatted"
* - -use-the-force-luke=tracksize:size option by suggestion from K3b;
* - -use-the-force-luke=wrvfy for WRITE AND VERIFY(10);
* - -use-the-force-luke=4gms to allow ISO9660 directory structures
* - more sane sanity check for -use-the-force-luke=tracksize:N;
* - -use-the-force-luke=break:size to set Layer Break position for
* - -use-the-force-luke=noload to leave tray ejected at the end;
else if (!strncmp(opt,"-use-the-force-luke",19))
...or consult the manpage, again:
"There're several undocumented options commonly denoted with
-use-the-force-luke prefix. Some of them serve debugging purposes. Some
require certain knowledge about recording process or even OS kernel
internals and as being such can induce confusing behaviour. Some are to
be used in very specific situations better recognized by front-ends or
automated scripts. Rationale behind leaving these options undocumented
is that those few users who would actually need to use them directly
can as well consult the source code or obtain specific instructions
elsewhere."
