Yep, I'm inclined to agree. I think I've decided on the SCSI disc naming scheme: /dev/dsk/sd_h0c0t0u0p2
The "dsk" is compatible with Solaris, IRIX and HP-UX. The "sd" is needed because /dev/dsk is going to have non-SCSI discs (IDE, floppy, MD and so on).
Also, I'm inclined to put CD-ROM in /dev/dsk too. After all, it's a compact *disc*, and is a FS-mountable device like all the others.
Regards,
Richard....
