the eject command in f16 says
# eject
eject: unable to find or open device for: `cdrom'

f16 has no cdrom or dvd entry in /dev,
so after each boot I have to manually
create the symlink to sr0.

Is there a way to make the symlinks permanent in /dev?

Do you happen to have a /dev/cdrom1?

lrwxrwxrwx 1 root root 3 Jun  7 15:55 /dev/cdrom1 ->  sr0

but the eject command wants /dev/cdrom.

What are the contents of, or do you have, the
/etc/udev/rules.d/70-persistent-cd.rules

file?

The stock f16 /etc/udev/rules.d/70-persistent-cd.rules   file contents are:

# This file was automatically generated by the /lib/udev/write_cd_rules

2 choices....

alias eject='eject /dev/cdrom1'

or

modify the lines in 70-persistent-cd.rules to swap the definitions.

OK, I modified the file, but the comment also says:
# You can modify it, as long as you keep each rule on a single
# line, and set the $GENERATED variable.

So, where should the GENERATED variable be defined
and to what value?
