On a cgroups v2 host, earthly fails to start with: Error: build new buildkitd client: maybe start buildkitd: wait until started: buildkitd crashed, and the daemon logs show CGroups V2 - sh: write error: Not supported. Earthly's bundled buildkitd could not initialize on cgroups v2 systems in older versions (0.7.2 hit this).

Upgrade Earthly to 0.17.4 or later: the reporter confirmed the cgroups v2 buildkitd crash is gone there (both the hello-world example and a personal project run). The broader cgroups v2 support for KIND and systemd images landed in v0.6.11, and the remaining buildkitd crash class was resolved by 0.17.4.
