# Omarchy: the build image compresses with zstd at its default level. Maximum

  # 26.9.1 started shipping a systemd unit under /lib, and owning /lib -- a
  # symlink owned by the filesystem package -- makes pacman refuse the whole
  # transaction. The unit is also a no-op here: its setup script apt-installs
  # Docker and the NVIDIA Container Toolkit and exits on any distro but Ubuntu
  # (install those yourself; see optdepends). Delete it, and its parents once
  # emptied; then anything else left outside opt/ and usr/ -- whatever its
  # type, an empty bin/ or lib64/ included, since those are filesystem-owned
  # symlinks too -- stops the build rather than shipping the next conflict.
