Yep, the libostree manual suggests converting contents in /var to systemd tmpfiles snippets: https://ostree.readthedocs.io/en/latest/manual/adapting-existing/ And that's in fact what rpm-ostree does: https://github.com/projectatomic/rpm-ostree/blob/bff3a54e1ee67398bd7a2cfdc359326689479954/src/libpriv/rpmostree-postprocess.c#L556 _______________________________________________ systemd-devel mailing list systemd-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/systemd-devel
