Ok /mnt/cdrom built.

Ok it says:

mount: block device /dev/sr0 is write-protected, mounting read-only

#ls -lag /dev/sr0 <returns>
brw-rw----+ 1 cdrom 11, 0 Aug 16 15:59 /dev/sr0

Yep,

Ok there are 2 dvd drives that use to work with sysfs and a .30 kernel
now the 2.6.34-gentoo-r1 kernel is not working, and sysfs was removed
as was suggested in the old console logs upon booting.

Of the many Gentoo systems I manage, most have 2 dvd drives. Very few
are working since I removed sysfs and built 2.6.34-r1 kernels.....?
