Hi Eric, I am replying to this -quite old now- post : https://lists.freebsd.org/pipermail/freebsd-hackers/2015-March/047486.html > More importantly, the EFI loader doesn't seem to make use of its > command-line arguments at all. But a ZFS-enabled loader would really > need the ability to take arguments from boot1 (or grub, or whatever > else). where you were suggesting it would be interesting for the EFI loader to make use of its arguments, which is still not the case. We've faced a similar problem here, where we needed the EFI loader be able to locally override the root-path offered through BOOTP. A quick fix would have been to hardcode the root-path but instead we chose to pass it through an argument to the loader (which then sets a new environment variable : dhcp.root-path.override). Find attached the two -simple- patches that allow such an operation. I don't know if they can be interesting for you or for upstream inclusion (though they are probably *not* ready for direct inclusion yet).
