Investigating why computer boots in SAFE MODE

    Is there documentation somewhere which details exactly what conditions
    would trigger 10.4 (Tiger) to boot in safe mode without the user
    pressing the shift key ?

    This has been happening to me for a few days now. I have no problem
    doing sudo, even managed to loging as "root" etc.

    Yesterday, I seemed to have fixed it by going into system preferences
    and reselecting my boot drive/OS. (this is on a PPC).

    Today, that trick didn't work. However, pressing command-S during boot
    didn't get me to single user mode, it good me a clean boot not in safe
    mode :) :)

    I know that the clock battery is weak. Unplugging the machine for
    maintenance causes the clock to think it is in 1970. However, if the
    machine remains plugged it, would a weak battery still cause havock ? I
    added a "-v" to the boot-args in NVRAM, and that value stays in there
    (indicating the nvram doesn't get zapped).

    the rc file looks for an environment variable SafeBoot . Does anyone
    know where that variable is set ?

    Yes. That battery isn't weak, it's basically dead. Replace it and your
    problems should be solved.
