I'm sorry, I'm running a home mail server using a dynamic IP address and
a lot of spammer listing services don't like that, it probably failed to
deliver the e-mail because of that...

Yes, it does. It took about 4.5 minutes to build a 4.4GB image.

But it seems like Brasero uses growisofs, and AFAIK growisofs doesn't use
libisoburn to make the image, right? Even more, installing xorriso
I realized I didn't even had libisoburn1 installed, so I guess braser
couldn't possibly make the image using it. Is there any point on trying
this?

Thanks!
