The bug saved my drive fortunately. Yay for that.

Don't worry about it. It was my poor attempt at tongue-in-cheek humour
:). Just lost one CD-R. The drive is still working fine, i think.

I see what i missed. I had no idea that 800MB or even 900MB CD-R
existed. Have only seen 700MB CD-R. Which explains my disbelief that
Debian would make a cd iso that couldn't fit into a standard cd. My
bad. But still it is a surprise to me that nobody thought this
deserved a mention in the release notes. I wonder if we are seeing the
last of CD-R as a Debian install medium. Wait, there is still the mini
iso. Ha, CD-R will live on. :)

I appreciate the detailed reply very much. Thank you for taking the
time. You have a nice day too.
