Anyone know how to disable just cdrom polling (i.e. automounting) in

cannot seem to find the solution.
(Slightly off-topic.)
AFAIK, the CD/DVD drive isn't polled anymore. It's the device that
informs the OS when a media is inserted. But I guess this assumes you
aren't using a drive from 1997 or such.
It is not off topic.
It is difference between telling OS that media is changed when asked and
actively sending notification when media is inserted without being asked.
According to hal-disable-polling manpage the second is missing:
"Despite the existence of support for asynchronous media change
notification in recent MMC (Multi-Media Commands) specifications, virtually
no optical drives are compliant with the specification. Fortunately newer
SATA ATAPI hardware seems to support Asynchronous Notification (AN)
and at this time of writing (March 2007) work is underway to make both the
Linux operating system kernel and HAL take advantage of this."
