After I did mkdir /dev/cdrom:

root@0[etc]# ls -la /dev/cdrom
total 40
drwxr-xr-x 2 root root 4096 Aug 9 21:12 .
drwxr-xr-x 13 root root 36864 Aug 9 21:12 ..

What is that?

I don't know if this is right, again.

And now this is what I get :

Could not mount device.
The reported error was:
mount: special device /dev/cdrom1 does not exist

Could not mount device.
The reported error was:
mount: /dev/dvd is not a valid block device
