Also note that it seems like there is currently nothing to create that
symlink. It seems like kernel passes only names like /dev/cdrwX where X
is steadily increasing. Only /dev/cdrom seems to be useable as a
constant filename but for many people their cdrom reader is not the same
as writer.

I think we have a problem here. As a workaround, I am going to add a bit
code to parse /proc/sys/dev/cdrom/info and pickup the first CDR or
DVDR capable device there (depending on the track size, IMO).
