Hi all,

When I do an ls -l for /cdrom, I get the following: lrwxrwxrwx 1 root root 9 Jan 21 17:16 scd0 -> /dev/scd0

When I do an ls -l for /dev/cdrom, I get the following: lrwxrwxrwx 1 root root 8 Feb 13 10:18 /dev/cdrom -> /dev/sr0

fstab contains: /dev/cdrom /cdrom auto ro,noauto,user,exec 0 0

So, my question is: why is /cdrom set up this way? I installed my scsi dvd and just made /dvd, and created a symlink for /dev/dvd -> /dev/sr2 . Do I need to do anything differently?

If it's working don't "fix it" :-)

Different device names can be used for the same device depending on it's function.

I'm not sure that it _is_ correct. Kscd doesn't have access permissions to /dev/dvd or /dev/cdrw even though they are chmod 777. So I was looking around and wondered about that...

My .02 here is that if you run strings on kscd, it is _LOOKS_ to be hard coded for /dev/cdrom..So your /dev/dvd, or /dev/cdrw wont work.. Use xmms to play audio from those devices if you have them hooked to your sound card.. also notice that /dev/scd0 and /dev/sr0 have the same major/minor numbers.. so, they are the same device... Why? Im not sure why we have 2 names.. Maybe someone else can answer that. have fun ;) Jim

I think maybe one is a raw SCSI device and one is not, but I could be wrong. Hopefully someone out there can clear this up for us. :-)

Nope.. After poking around a bit here is what I see... They are the same device right, not raw or other, because the have the same major/minor #.. Looks like some distros use /dev/scd0 and some call it /dev/sr0.. look in /usr/src/linux/Documentation/devices.txt and check it out.. Regardless, they are the first SCSI cdrom..
