Comment # 1 on bug 1225709 from Richard Brown

This is because we use : as a delimiter where analysing the disk metadata..so
the :0 is interpetted as the next field, not as part of the device

Either we'll need to rework that functionality, or just filter out all usb-
devices so the problem doesn't occur

Given the UEFI ESP standard we use is for permenant installations, some UEFI
firmwares may not appreciate an Aeon OS disk being removed, so maybe we
shouldn't support removable devices

Leaving these thoughts here for discussion, not expecting to move on this bug
quickly
