Okay, that allows me to create a storage partition where I suppose I could put scripts that I wanted to run, but it still doesn't let me change any settings. I can create partitions and name them /home, /users, etc., but as soon as I reboot, it loses the mount points on them, because, again, I don't actually have any access to fstab. When it says 'saving changes to fstab' it's really just saving to RAM, so after reboot, I just have two generic mount points in my /mnt. Any other thoughts?
From what I understand, it is impossible to unmount / and remount it in rw mode. I think what I'm going to be looking for (although I don't know if it exists) is a utility or something that will let me modify the file-system externally.
