Este pequeño tutorial fue probado en CentOS 5 pero funciona para cualquier versión de Linux, al final la consola es igual para todos.
Para quemar en consola, necesitamos contar con una quemadora de CD/DVD, Bastantes CD/DVD donde quemar, lo que queremos quemar y los siguiente programas que instalamos a continuación.
# yum -y install mkisofs cdrecord
Necesitamos crear una .ISO de lo que deseamos quemar. para esto utilizamos el comando mkisofs
# mkisofs -r -l -o imagen_que_quiero_crear.iso /home/data_que_quiero_quemar
Mas o menos nos saldrá la siguiente información
INFO: UTF-8 character encoding detected by locale settings.
Assuming UTF-8 encoded filenames on source filesystem,
use -input-charset to override.

Antes de proceder a quemar primero necesitamos identificar el dispositivo (en este caso la quemadora) entonces escaneamos el dispositivo
# cdrecord -scanbus
