    I'm pretty sure this is the default. I haven't need to make this change
    since FC2 I think.

    This was implied by "only allow me to logon". What I should have written
    is "Only allow my account to logon". lol

    This is a great idea but I'm unable to implement it. Many of the machines
    I end up using don't have USB. :(

    > -Turn off all unneeded services

    Yes, I will add "Install only needed apps." I do this anyway but I should
    list it.

    SSH is not enough? I only need shell access remotely.

    Humm. I'll have to research this one. I was not aware of that limitation
    for EXT3.

    Thank you for the tips.
