    Phoronix: F2FS File-System Adding Zstd Compression Support In Linux 5.7

    Being introduced by Linux 5.6 is optional F2FS transparent data compression support that was implemented with LZO and LZ4. Now for the Linux 5.7 kernel there is Zstd compression support on the way...

    Nice, but there is one key ingredient missing: lack of U-Boot support. Unless that's patched in many IoT devices will not use it. I myself kept to ext4 because I want the boot files in filesystem.

      Why cant *Buzzword* devices not use a boot partition? Its the sane thing to do, along with having your basic rootfs as read-only squashfs/erofs.

          That. I always find myself going back to ZFS or BTRFS because of that one feature.

          I'm hoping that Stratis will assist XFS in getting that feature.

            U-Boot doesn't even need a partition, just offset for downloading binaries from a block device.
