Thanks, Mikkel, but my /etc/udev/rules.d/70-persistent-cd.rules does
not look as you describe:
# more /etc/udev/rules.d/70-persistent-cd.rules
# This file was automatically generated by the /lib/udev/write_cd_rules
# program, probably run by the cd-aliases-generator.rules rules file.
#
# You can modify it, as long as you keep each rule on a single line
# and set the $GENERATED variable.
