Grub-mkconfig failed when I install 21.3

Support

1

I install manjaro 21.3 today. I need a fs that support compression and encrypt, so I use F2FS for my rootfs. Because grub cannot correctly read its boot files from an F2FS partition that was created with the extra_attr flag enabled, I created a EXT4 partition with mount point /boot.
Calamares wouldn’t enable compression and encrypt for me, so I created a shell script to do this.

cat /usr/sbin/mkfs.f2fs                                                                                                                                      #!/bin/bash

/usr/sbin/mkfs.f2fs.real -O extra_attr,inode_checksum,sb_checksum,compression,encrypt $@

After partition, my disk look like:

sudo fdisk -l /dev/nvme0n1
Disk /dev/nvme0n1: 476.94 GiB, 512110190592 bytes, 1000215216 sectors

But grub-mkconfig failed. From calamares’ log, I saw

So, what’s wrong with my installation? How to fixed it?

The system tries to access the grub background theme before the kernel and the initrd is loaded.
This file is located on the root partition.
GRUB_THEME="/usr/share/grub/themes/manjaro/theme.txt" must be set to
#GRUB_THEME="/usr/share/grub/themes/manjaro/theme.txt".
Then try again.
Can you show /boot/grub/grub.cfg ?

Wow, I uncomment GRUB_THEME="/usr/share/grub/themes/manjaro/theme.txt" in TARGET_ROOTFS/etc/default/grub, my installation is successful!

This is strange, because I check the boot/grub/grub.cfg.new file in target rootfs when grub-mkconfig failed, the failing script is etc/grub.d/41_snapshots-btrfs:

sudo tail /tmp/calamares-root-nxgionwh/boot/grub/grub.cfg.new

### BEGIN /etc/grub.d/41_custom ###
if [ -f  ${config_directory}/custom.cfg ]; then
  source ${config_directory}/custom.cfg
elif [ -z "${config_directory}" -a -f  $prefix/custom.cfg ]; then
  source $prefix/custom.cfg
fi
### END /etc/grub.d/41_custom ###

### BEGIN /etc/grub.d/41_snapshots-btrfs ###

All though grub-mkconfig is successful, update-grub is failed:

postcfg remove amd-ucode, so I can’t boot to the system when update-grub was failed.

So I manjaro-chroot to the new system, and run update-grub manually. Update-grub successful.

I can run grub-mkconfig and update-grub in chroot environment successful, but calamares run them failed. I think the manjaro installation need to improve.
BTW, when I partition manually, calamares pass the -l option to mkfs.f2fs, but with no label argument! It’s a bug.
