This will happen for non-RockRidge CD-ROMs (such as any Windows CD
ROM, for instance).

The bare bones format of CD-ROMS is called ISO9660, which doesnt
support a lot of things like long filenames, etc.  So there are
extensions.  MS uses their own - called Joliet - and the rest of
the world uses "RockRidge", which allows you to have sym links,
real Unix permissions, etc.

Add a "mode=0444" to your mount line (or in the /etc/fstab file).
This should do it.  In fact, that is the default, so you probably
have an existing mode= line in /etc/fstab that you may as well
remove.

If this is happening on a Linux CD (RockRidge) then there is
something else wrong.
