Hello, Grub doesn't support partitions with ext4 and the large_dir feature enabled (it will error with unknown filesystem). This is true for both grub-install and if trying to boot a partition with large_dir (i.e. the Linux image is on there, not in the same partition as Grub).
(This bit me rather hard when enabling this on a system and then unable to boot to it. To workaround I had to move the Linux and initrd images to the same partition as Grub and rewrite the configuration. large_dir can't be set off as far as I can tell. This is not ideal for my current setup on Guix, but should be able to work around it with some help.) Since large_dir has been around for some time, and supported in the kernel since 4.13, are there any plans to support this in Grub? I would say this seems very reasonable, but unfortunately do not know enough about the internals to see what work is involved. Thanks, John PS: Please also cc me directly as I am not currently subscribed to bug-grub.
