I suppose it just reports "not ready" on the CD LUN if you've got DVD-RAM media in the drive?

Yeah, use disklabel to partition it, and then use newfs. My guess is that sysinstall is doing something that accesses the raw device in 512 byte chunks, which of course doesn't work for devices with a 2K blocksize. I'm working on DVD-RAM support in the CD driver, so you won't have to enable multiple LUN support on your DVD-RAM to get it to work. (You'll be able to read/write with the CD driver.) The main hangup is what to do about disklabel support. I haven't worked on it in a few weeks, since I've got other more pressing things to do. So using the da driver is the right approach for now. It should be able to handle 2K blocksizes okay, you probably just need to use disklabel and newfs on the drive instead of trying to use sysinstall. (I'm not sure what it is doing in 512 byte chunks that causes the problem.) > Btw: when's UDF ready? :) Ask Julian, I think he said he was being paid to work on it.
