I have a small embedded Linux device where the root filesystem is mounted over a USB connectionthe device can handle a reset quite well (it'll wait for the USB disk to arrive should it be unplugged at boot)however should the disk be unplugged the device tends to wedge,  I'd prefer if it just reset?is there a kernel option that would get the kernel to reset should the primary disk disappear?
is there a way to reset a linux machine should the primary disk fail?
