You can try taking an older image, and compiling systemd, and running the tests.
Even something as simple as
sudo dnf build-dep systemd
git clone https://github.com/systemd/sys
meson -Dman=false build && ninja -C build && ninja -C build test
If that passes, then the next step would be to take that older image,
install just the newer kernel, and repeat the tests.
Here's a quick update, since I may not be able to get back to this until early next week. I was able to build the version of systemd that is in the master branch of the GH repo, SHA: 8255430. All tests that were executed pass under kernel 4.16.16-300. About 10 tests were skipped. The following skipped tests seem to be of particular interest:* test-udev* test-boot-timestampsI was able to insert an "assert_se(1==0)" after the line that triggered the assertion when booting from the installer, and numerous tests fail. So that code is at least getting exercised.Installed the latest version of the kernel available for F28, 4.17.3-200, and test results were the same. I am now trying to build 4.18.0-0.rc3, since that appears to be the latest version in rawhide.
