It seems like it is- if the standard ATAPI ioctls work, but the SCSI commands
don't, wouldn't that be a bug in the scsi emulation? On another interesting
aside, the standard cdstop/cdplay/cdpause stuff that come with Debian 1.3.1
work fine in ATAPI mode, but return an `invalid ioctl()' error when run with
SCSI emulation. The only program that seems to like scsi emulation mode is
cdrecord (lucky for me) - but when I tried the latest version of cdrecord, it
did not work - couldn't get disc type or something. I'm using 1.6a7 just fine
though. So, it seems to me like the scsi emulation is very broken or there is
some other factor that I'm not aware of- is there anything I can do to help
pin down the source of the problem?

How is that going to work? Will the ATAPI cd-rom _and_ scsi emulation be built
as modules, or will ATAPI cd-rom support be in the kernel with the scsi
emulation as a module?

It's version 0.8betaSomething - standard in Debian 1.3.1r6. I think I have the
URL for cdparanoia, but thanks for the pointers.
