    I'd like to make a bootable USB drive with some disk utilities and such - but the only thing that comes up when I search is how to create a bootable install disk - which is not what I want, I'd like to use some 3rd party utilities, not just apple's.

    I'd also like to keep the system as compact as possible. Can anyone help me out with the minimum resources needed to make a bootable system for Lion? (i also have snow leopard and can use that in a pinch).

    You can use Recovery Assistant to create a bootable USB with Recovery of Lion just like the RecoveryHD in internal HD. It is a base system and only need a minimum 1GB USB.

    Thanks for the answer :) but this isn't what I want, to clarify - I want to install a mini system folder on a usb drive, that will boot and let me run my own programs.

    nothing really special required, just make sure the usb drive is big enough to hold the full installation. 16gb+ should be fine. make sure your usb media is attached, launch the lion installer, then make sure you select the usb media as the installation directory.

    Yeah, I guess thats what I'll do. I bought the wrong size thumb drives and I was hoping I could shrink the system down to something nice and tidy that would fit on them :) I can go buy bigger ones, but now the idea of a minimal system intrigues me, I'll have to do some more research.
