Yes, looks like I would have to modify scsi_debug.c DEV_READONLY to make
it behave as read only.

It is named scsi_mod.ko if you built it as a module.
Once you have a base .config it is easier to modify the .config and then
run make oldconfig and answer y/n/m.
I usually just delete the line in question from .config, and run make
oldconfig. In this case delete the line with CONFIG_SCSI and run make
oldconfig.
