sr* is no mystery in that sense, although, a cdrom IS a block device not a scanner or a tty. He is right that if GKH's argument about consistency is to hold much water, optical media should be just yet another flavor of sd*, the fact that it's read-only and needs special handling to write
But it uses another "command set" or "protocol" (on top of scsi transport layer) than harddrives. ISTR that once I put in a DVD-RAM disk (DVD-RAM, in contrast to crap DVD-ROM is a random access writeable medium and all this is handled transparently by the drive's firmware, no need for magic incantations and dealing with strange tools), my DVD drive becomes a "normal" block device and I can access that dvd-ram via sd*, but I'd need to check if my memory serves me right. I think my "TCP vs UDP, both using the IP protocol but being different things" analogy was not too bad to explain the difference. -- Stefan Seyfried "Dispatch war rocket Ajax to bring back his body!" -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-factory+help@opensuse.org
