Do you have a bootable installer of the OS on a USB drive?

    Is it recommended to make one? If so, how large of a thumb drive is required?

    IMO, absolutely good thing to do.

    Clean OS: 8 GIG.

    No, I don't. I do have one on an SDXC card, though. ;)

    Will the Recovery Disk Assistant program allow for the same thing or does it only work with the current OS running (i.e. if I upgrade to ML, it'll only work with ML)?
