Yes, that is the issue I'd like to avoid.
Not a problem when the power fails and returns but it IS a problem if I issue a 'restart' / 'reboot' (can't remember which is correct but you get my drift) command from a remote SSH session.
I'll try your install to MemKey suggestion, since I don't have an HD present on this box.
Thanks,

I made a quick script you can use to prevent the ejecting. You just need a way of running it before you issue a reboot.
| Code Sample |
#!/bin/bash
#
# Quickly change knoppix-reboot to prevent cd eject
#
# Remove sym-link to /KNOPPIX/ copy from /ramdisk/ copy
sudo rm -r /etc/init.d/knoppix-reboot &&
# Copy original RC script to /ramdisk/ copy
# sudo cp /KNOPPIX/etc/init.d/knoppix-reboot /etc/init.d/knoppix-reboot &&
sudo cat > /tmp/knoppix-reboot << COSMIC &&

Copy that entire thing into a file, and then "chmod 755 [filename]".
Everything uses sudo. If it fails, it should tell you. All it does, is removes the original symlink, creates a new temp copy (I tried to use a diff/patch, but it kept failing for no reason, only inside of the script), moves it over, then replaces a second symlink. Let me know if it works.
The gist of it is that I removed the actions of ejecting the cd and waiting for enter to be pressed.
It would still be better to try a usb flash drive, imho.
Edit: This copy of the reboot script is from 3.4.11, so I don't know if 4.x has any differences.
