FreeBSD worker upgraded to FreeBSD 15.1

rosemary (the freebsd-x86_64 cluster worker) has been upgraded from FreeBSD 15.0 to 15.1, chiefly to move OpenZFS off the 2.4.0-rc4 release candidate that shipped in 15.0 onto the stable 2.4.2 in 15.1, while investigating rare transient build failures.

  • Host upgraded 15.0-RELEASE → 15.1-RELEASE (OpenZFS 2.4.0-rc42.4.2)
  • obuilder ZFS pool wiped and recreated; base images rebuilt on 15.1: freebsd-15.1-ocaml-4.14 (4.14.4) and freebsd-15.1-ocaml-5.5 (5.5.0, the default)
  • ocaml-ci and opam-repo-ci updated to request the freebsd-15.1 images
