When I woke up this morning, I thought, maybe I need to do load_env in the new config instead of the menuentry of the old config. Then I saw your response with the same thing. I thought about doing some fancy detection stuff like 10_linux does to re-export $prefix, but decided against that as I didn't want to mess with the detected root device at boot. I didn't need any other things like password protected boot or anything that could need an updated $prefix, so I just took the easy way out and did this. --- /root/00_header 2017-03-04 09:25:34.974046629 -0700 +++ /etc/grub.d/00_header 2017-03-04 09:27:06.479049038 -0700 @@ -45,8 +45,8 @@ cat << EOF set pager=1 -if [ -s \$prefix/grubenv ]; then - load_env +if [ -s /snaps/rxe-boot/grub2/grubenv ]; then + load_env -f /snaps/rxe-boot/grub2/grubenv fi EOF if [ "x$GRUB_BUTTON_CMOS_ADDRESS" != "x" ]; then That does exactly what I want.

Didn't know about that command.
