I'm getting this error when trying to build a kernel that has "Kernel

I could live without it. It is required for RestrictFileSystems= in
systemd service units according to
<https://github.com/systemd/systemd/blob/main/README>. But is there an
easy fix?
I'm currently using ptxdist 2024.03.0 but is also reproducible on the
ptxdist master branch.
