Fedora obs-repos fails with systemd.gpg not found

[immuter]

On a clean particleos system, setting mkosi.local.conf to

[Distribution]
Distribution=fedora
[Config]
Profiles=obs-repos

results in systemd.gpg not found.

Looking at mkosi.profiles/obs-repos/mkosi.conf.d/fedora/mkosi.conf.d/rawhide-tools.conf, which contains

# SPDX-License-Identifier: LGPL-2.1-or-later

[Match]
ToolsTreeDistribution=fedora
ToolsTreeRelease=rawhide

[Build]
ToolsTreeSandboxTrees=systemd.gpg:/usr/share/pki/rpm-gpg/systemd.gpg
                      rawhide.repo:/etc/yum.repos.d/systemd.repo

We can see it is looking for these in mkosi.profiles/obs-repos/mkosi.conf.d/fedora/ not mkosi.profiles/obs-repos/systemd.gpg and mkosi.profiles/obs-repos/mkosi.conf.d/fedora/mkosi.conf.d/rawhide.repo. Confusingly other files in the same directory look to different locations.
