Well, that's manky - it should be a link to "cdroms/cdrom0", not
"../cdroms/cdrom0".

This is what I don't understand.  You should be able to...  however,
it's almost definitely being recreated by devfsd, so you should poke
around in /etc/devfs to find the broken configuration file and fix
it.  And file a bugreport.

On my (Debian) box, /etc/devfs/devfsd.conf contains the line:

REGISTER ^cdroms/cdrom0$ CFUNCTION GLOBAL symlink $devname cdrom

... which is what creates the /dev/cdrom symlink. (It means "when the
kernel or a module registers a CD-ROM device, create a link to the
device name from 'cdrom' in /dev").  You should have something
similar, or if Mandrake ships with an older devfsd, it might be in the
"symlinks" file or the "symlinks.d" directory under /etc/devfs.

I suggest having a good read of the devfsd documentation; it's
actually pretty elegant.

There's something deeply unconvincing about an aftershave called Kevin.
