I've committed a set of patches in -current that provide write support for randomly writeable CD-type drives. (Mainly DVD-RAM and PD-type drives.) The driver should function the same as before with read-only media. It is now possible to do things like burn a UFS disklabel and filesystem on a CD-R, or disklabel and newfs a DVD-RAM disk. The disklabel semantics may be a little confusing with writeable media, since until you actually put a disklabel on the disk, you'll see the faked-up disklabel when you type 'disklabel cd0'. (With the da(4) driver, for instance, you wouldn't get any label back in that case.) This may be helpful in creating a label, though, since you can do something like: disklabel cd0 > cd0.label vi cd0.label [ modify the label somewhat ] disklabel -rR cd0 cd0.label Anyway, feedback and comments are welcome.
