Please note that it doesn't matter if it's Joerg's Officially Blessed Cdr=
ecord
or not - the question is if userspace should be able to cause that error
to happen  *at all*.

Also, it's quite possible that we're looking at a *kernel* regression, th=
at
the userspace software managed to actually *work* with previous kernels, =
even
if it wasn't blessed by you:

If it breaks when somebody upgrades their kernel, it's probably the kerne=
l's
fault, not the user's fault for using a distro that ships The Other Fork.=

Yes, but his distro probably feels it can't ship the original cdrecord
so it ships wodim instead.  And if it's indeed a kernel bug, replacing
a forked userspace program to work around a kernel bug is The Wrong Answe=
r.

It forked 3 whole years ago, Joerg.  Let it go already. And if you can't
let it go, at least ask the user *helpful* questions, like Jeff Garzik di=
d:
