That does not match the behavior I observed; it definitely successfully installs the bootloader when passing the raw device rather than a symlink. Which I can only think of a small number of conditions that would trigger that sort of behavior... I'm fairly confident in this because I've been experimenting with two incompatible u-boot bootloaders on the same boot media (one for pinebook, and one for pinebook pro) and a successful installation overwrites the bootloader, resulting in the expected machine booting, and the other machine not booting. With a symlink it doesn't install to the raw device at all... That said, I'll move on to testing your next patch. :) live well, vagrant --=-=-= Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iHUEARYKAB0WIQRlgHNhO/zFx+LkXUXcUY/If5cWqgUCX5LzbwAKCRDcUY/If5cW qhFzAP9584ajRl0cA8xYDHOB8Z+2b9c2curDnEfnGNcP2O07qQEA+70HFDHKN3qm KOIb9reADaeFkIIRxYGdoV3jMhUlGwA= =6hT6 -----END PGP SIGNATURE----- --=-=-=--
