Yea - volume.label is merely one of gazillions of things you can test.
No doubt it would also be possible to simply ignore device /dev/sr0
as well (or something like that). Look in /bin or /usr/bin for programs
names *hal* - I think there is one out there which will give you a
listing of all the hal device attributes and such, and I believe any
of them can be tested for in the policy files (but I am by no means
any kind of expert - there is a hal mailing list out there where I got
help to enable me to construct this specific case).
