        Heya, everyone.. 

        I've run into a bit of trouble, trying to burn a CD, using my CDRW, 
and devfs. I've tried using 3 different versions of cdrecord (1.8, 1.9, and 
1.10a4), with all of them giving me the same error. All the proper modules are 
loaded, devfs is compiled into my kernel, and I have followed all the 
documentation I could find. the CD-Writing HOWTO barely mentions DevFS, and 
hasn't been updated since July 23rd, so I'm kinda stumped. Here's what I have:

First, my modules:

dmesg shows what devices I have:

        With the sg module loaded, according to the CD-Writing HOWTO, I am 
supposed to write to /dev/sg0, which I have linked /dev/cdrom (note: not 
cdroms) to.

        cdrecord -scanbus give me:

        So, I have my CDRW seen. 
cdrecord -v dev=0,0,0 speed=2 -data cdr.image blank=fast (for my CDRW disk) 
gives me:

        This DOES WORK, when I do not use DevFS. I would rather try to get 
this to work, rather than mount devpts, disable devfsd, and reboot, so I can 
burn a CD. Has anyone tried doing this, or have had any similar problems? I am 
doing this on kernel 2.2.17, with devfsd-1.3.10 and devfs-0.99.18.

                                                        BL.
