Okay, that turned out to be the grub-mkimage I was using, not the actual GRUB2 modules. We're now back to seeing the original problems from https://bugs.debian.org/711799#14: > * no DHCP-assigned network settings copied in from the PXE environment > * no TFTP server IP copied in from the PXE environment and as a result, not being able to fetch grub.cfg Regards, -- Steven Chamberlain steven@pyro.eu.org
