As I understand this, systemd expects daemons to deal with no settings in
/etc and /var.

Tempfiles.d is the proposed clutch till that is actually the case.

I just copy my keyring into /usr/lib/factory/etc and restore them from
there as needed. The private keys should stay on the server creating the
image, but currently I just put those into the package as well... I need to
change that ASAP. In my defense: There are no users on any of the machines
running those images that I do not trust.

I do not consider this a problem. When you use somebodies images you need
to trust that person. I do not consider trusting the keys that person
provides to be a problem.

Any privileged process can mess with /etc at any time. With factory reset
at least you get a pristine copy to compare the files in /etc against.

Arch did embrace systemd, it should make it easy to use all its features. I
am not proposing to enable them by default.
