Bug description:
  As per https://github.com/openzfs/zfs/issues/15930

  ZFS and kernel 6.8 seem to throw EOPNOTSUPP on calling
  copy_file_range, breaking a multitude of applications.

  Upcoming noble (24.04) appears to currently include kernel 6.8 and ZFS
  2.2.2.

  One notable issue is when running Root on ZFS: systemd-sysusers will
  always fail to create users/groups with the error "Failed to backup
  /etc/{group,passwd}: Operation not supported" due to the call to
  copy_file_range.
