Anne, mtab should be dynamic, written by the system, based on mounted partitions/drives.
To verify this, open a terminal window and su to root. Presuming that your LS120 is mounted: Open /etc/mtab and take a look at how it lists your LS120. Close the file, making no changes. Next, make a copy of your current /etc/fstab file (e.g. fstab.original). Then open and edit the line referring to your LS120, setting it to match the /dev scsi-emulation entry. Save the altered fstab file (as fstab). Now issue the command: umount /mnt/LS120 (or whatever it's called in /mnt). If you open the /etc/mtab file now, you should no longer see the LS120 listed. Close the file without making changes. Issue the command: mount /mnt/LS120 (or appropriate). Again, open /etc/mtab. You should now see the LS120 listed at the bottom of the file with the new settings you just gave it. Presuming that all is, as listed above, you can test to see if your system and the LS120 will play nicely with the new settings. If they don't, simply copy the fstab.original to fstab, unmount and remount the drive and you should be back to the way it was before starting the experiment. I run 9.0 with supermount with no problems (hda, hdb, dvd, cd-rw, iomega zip drive). I was reluctant to change the settings for the dvd drive to scsi emulation...but finally make the change to lilo and fstab (thank you, Malcolm, for the push). I even 'moved' the cdrw from scsi0 to scsi1 in fstab and set dvd as scsi0 (it's the master on the bus). All is working well and I now have a reader and writer in xcdroast and mdk install recognizes and installs from dvd drive, as before. I'm not sure whether this has any effect or not...but this box is an (ugh!) HP Pavilion, 500 MHz that came with cable select set on the drives. When I dumped the 19GB bigfoot and installed 2 IBM 40GB drives, I was too cheap/lazy to buy new cables and install as master/slave on hds or rom drives.
