Comment 2 for bug 1913468

booted focal riscv64 image in qemu VM.

updated to proposed, and installed the new u-boot-menu 4.0.1ubuntu0.1

upgrades to u-boot-menu did not regenerate /boot/extlinux/extlinux.conf.

as there is no kernel to update, i triggered u-boot-menu update by calling

$ sudo u-boot-update

Checking the /boot/extlinux/extlinux.conf it was updated and now has Ubuntu branding, non-quiet boot by default, and earlycon options set. root= argument is also parsed without issues. however my fstab currently doesn't have any comments either.

rebooting.

Reading the above you can see that U-boot menu is now branded, and the boot is not quiet.
