No, I mean /dev/scg*.
If OS like Linux do not completely copy my ideas from 20 years ago (when
I did introduce SCSI generic passthrough), I expect that the users
are clever enough to replace this with their local name.
I cannot modify the man page for every OS.

I know that it is needed, that's the difference.
This is why cdrecord needs to be called with the right privileges.

Cdrecord needs this. CD/DVD writing is a real-time process.
Some newer drives may have workarounds but then the quality of the
media is not the same as it would be when writing uninterrupted.
If you Don't like to accept this fact, it is your problem.
But please don't complain if you have problems.

The Debian version is junk as it introduces Bugs that are not present in the
original.
Also the Debian maintainers are unwilling to cooperate :-(

But your main Proplem was caused by the fact that you ignore the official
documentation.
Your proplem is not present in case that you call cdrecord with the needed
privileges (as documented).
