Moreover, it tends to retain rather a lot of ‘false positive’ modules as well e. One of them might work. Keeping a timestamped backup via –snapshot-backup ensures that there’s no risk we run buildkernel twice between reboots, thereby losing our reference point.
You can investigate that by issuing lsusb as root:.
Note This kvcvideo an entirely optional step – if you’d like to skip it, simply continue to the next section now. Save and exit the nano editor. Ensure the boot usb key is still inserted, then issue:. Once none are, congratulations: Trying to add this issue to my tutorial on linuxintro.
