To add a pure users' comment to the story:
Maybe you should not overestimate cdrecord as a tool (like its author obviously
does sometimes). At least for DVD there are well-working alternatives.
If Joerg feels a better home on Solaris, so be it. It's his right to decide for
solaris, just as it is a users' right to decide against cdrecord.
