Hi all...

What is the relationship between the file /usr/src/sys/scsi/README and
reality?  It mentions a number of interesting things I haven't found
anywhere else, including a program /sbin/scsi which supposedly allows
probing for new scsi devices without rebooting.  Does this program
actually exist?  (It's not apparent in the -current source tree.)

Also, is anyone out there using removable-media scsi devices?  I've
been able to use a cd-rom and a 128MB optical drive pretty reliably,
but I haven't figured out how to change the media in the drive without
rebooting.  Is there some way to convince the kernel to let go of the
media (i.e. send an "allow media removal" command to the drive), and
lock it down again later?  

FWIW, I'm running the mac68k port.  (The relevant parts of scsi should
be architecture-independent, I think.)

Thanks for any info,
- monroe
