| Or is your problem really about the "Remove cd and press enter to finish rebooting/shutting down" message |

| You can write to /proc/cmdline? How? Never heard of that being possible.. |

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, Brian H. |
