01:46 < jmr2> Glanzmann: thanks for your various documents. I just tether-booted the whole chain for the first time, and it's quite fun to watch.
01:46 < jmr2> Two comments: 1) instead of deleting fbaa64.efi (I still have it without ill effects), you can uninstall grub-efi-arm64-signed and its dependencies.
01:47 < jmr2> 2) I couldn't get dpkg-reconfigure grub-efi-arm64 to install grub. I ended up using mps's --efi-directory instead of your --removable, since it uses a path instead of a device - less risky.
01:47 < jmr2> In the end, installing grub is three commands: apt-get install grub-efi grub-efi-arm64-signed- ; grub-install --target=arm64-efi --efi-directory=/boot/efi --removable ; update-grub
dpkg-reconfigure tzdata
# Fix grub
-apt-get purge grub-efi grub-efi-arm64 grub-efi-arm64-bin grub-efi-arm64-signed
-apt-get install grub-efi-arm64
-grub-install --removable /dev/nvme0n1p4
-# Set removable media to yes and nvram to no
-dpkg-reconfigure dpkg-reconfigure grub-efi-arm64
+# We deinstall grub-efi-arm64-signed- because it creates a file fbaa64.efi
+# which makes u-boot hang.
+apt-get install grub-efi grub-efi-arm64-signed-
+grub-install --target=arm64-efi --efi-directory=/boot/efi --removable
update-grub
-find /boot/efi -name fbaa64.efi | xargs rm
