I suspect this sounds like a strange question. A friend has a company that distributes his own catalogs on CD-ROM, and wants to build a mass-burning box (something like 8 CD/DVD burners), running linux. The problem is how to burn an image at the same time to all writers. I could write a script, but I think this would launch 8 reads on the same iso file, all desynchronized, that will drive nuts the disk. Is there any way to get all the /dev/sr? devices and build something like a fan-out device, or like a RAID1-CDROM or whatever ? I suppose it has to be done at the kernel level... TIA -- J.A.
