AW: ATAPI CDRW which doesn't work -> devfs problems

[Friedrich Lindenberg]

 Hi
 I was trying to burn cds under linux-2.4.1 with 
 devFS enabled. But x-cd-roast (and also cdrecord)
 do not find any scsi drives. I guess they have been
 renamed or something like that, I cannot find them 
 in /dev, nor anywhere in /dev/scsi ...
 Oh, and could anybody tell me, how I stop RH7
 creating /dev/lp* every time I boot ? I don't 
 use devices attached to lp* ....

   thanks & greetings,
    Friedrich

xcdroast expects to find a whole swag of sg device
filenames (/dev/sg[0-16], /dev/sg[a-q]) and scsi
cdrom names (/dev/sr[0-15]) when it starts. The
xcdroast tarball comes with a MAKEDEVICES.sh script to
create them. If they are not all there it seems to
get upset.

This is not very devfs friendly since its policy
is only to show /dev entries for devices that you
actually have connected and that a driver is 
controlling.

So the hack solution is to edit out of MAKEDEVICES.sh
those file names that you actually have then execute
it. IMO this is not a devfs problem, xcdroast needs an 
improved device scanning algorithm.

BTW the /dev/sga,b,c style of sg device names are
deprecated in favour of the numeric style.
