I would consider this advice or TCA at most If I have access to a system, I can compromise it anyways, and if there are trojan horses out there, a note in a manpage can't even hope to address the problem. "fast reboot doesn't zero out memory" is a good note, "fast reboot... alt BE...malicious trojan..." begs the question of why we don't point out all the *other* places trojans might bite you, as well as all the other potential social engineering, worm and virus risks that might or might not exist... Might as well stick a label on it that says "might contain nuts" just to be safe :-) Sherry Moore said: > I don't know the history behind the requirement stated above.

If anybody knows the answer, feel free to chime in. lu uses init.d K* scripts to copy volatile files and perform the magic needed to switch things under the covers so that the system actually reboots elsewhere (eeprom boot-env changes, grub menu updates, whatever) If you bypass those scripts with commands like reboot, halt and uadmin, lu can't switch BEs for you. -John
