I'm talking about resizing my root partition (/), while the system is on (I know that's usually impossible, but I'm just hoping there is some way to do it). I want to know if there is some way I can boot the system up in read-only mode (without a live cd, just in case), and resize /.
If it can't work, I understand, as that is what I already know to be the case (but you never know =P)
