What I am trying to do is boot a raid 1,5,6 system.
However that leaves no space for a boot drive. So...I thought I would install the the 2,3,4 drives as appropriate and then install the /boot on a usb stick.
In this instance a 1,2,4,8GB stick. Now since this is for raid drives if the stick is not plugged in the system will not boot.
But it does give me space in the system for the 2,3,4 drives but no boot device and no CDrom. This would be a usb/esata device.
So the usb 1,2,4,8GB device would act as the boot device. At least I was hoping that would happen.
I do not want to install anything but /boot on the stick, no system as such.
Hope this clears up any misunderstanding.
