The sysusers.d file shipped with this has:

  u systemd-journal-remote        -               "systemd Journal Remote"

But the tmpfiles.d fragment has:

  z /var/log/journal/remote 2755 root systemd-journal-remote - -
  z /run/log/journal/remote 2755 root systemd-journal-remote - -

There's no "systemd-journal-remote" group created...

This tool offers a --setup-machine-id flag, but it has very different
semantics from systemd-machine-id-setup. Both will call sd128_randomize,
but systemd-machine-id-setup will always prefer hardcoded UUIDs passed
into the host. For example, launching a qemu kvm with the -uuid flag
will cause the machine-id to mirror this -- though, this alone can be
problematic[1]

Is this behavior intentional? Does firstboot need to learn the same
rules? Do we just retire systemd-machine-id-setup?

Cheers,
