Hi,

GRUB has gained support for Zstd-compressed Btrfs file systems in 2.04.  It was added in commit "386128648 btrfs: Add zstd support to grub btrfs".

Could a maintainer please close this issue?

Thank you,

Maxim

As a workaround, could a btrfs subvolume for /boot be used that's being mounted with compress-force=lzo ? (note: assuming there's only one btrfs partition: the one for / and mounted compress-force=zstd or compress=zstd)
I haven't looked into it yet, but if anyone knows please say so.

This compression method is also relevant for squashfs and it would be good to support it there as well.

Linux 4.14 supports Zstd as compression algorithm for btrfs. Unfortunately GRUB doesn't support this configuration, meaning that is not possible to have a Zstd compressed root without a separate /boot partition.

As GRUB supports the other btrfs compression algorithms, it would really make sense to support Zstd too.
