Hi Warner, there has been an zstd update in ZFS that has already given me a lot of headache and postponed the whole commit by 2 months. As of our documentation, ZSTDIO should be included in kernel for ZFS: https://github.com/freebsd/freebsd-src/commit/fb702b4446023 Should we add options ZSTDIO to MINIMAL?
