You are trying to build something that requires at least specific git version of mkosi, I think, systemd I assume, since that's probably the only project using this feature out there at this point, so you must run mkosi from a git checkout.

Can you provide the debug output for the run from a git checkout with the SELinux problem?

@eadwu mkosi does not have a required dependency on git, using mkosi from within the systemd repository does have a required dependency on git as long as we're using features that are not in a released version so that we can ensure the mkosi version is sufficiently new and can show a proper error if it isn't. Please run mkosi from git for now when using it in the systemd repository. Hopefully at some point in the future we won't have to rely on unreleased features in the systemd repo anymore and can drop the git requirement.

As for the other selinux error, can you tell us a bit more about your setup? Specifically, the output of stat --file-system /var/home/sss/.cache would be interesting.

Got it, I see, error message confused me.

SELinux is disabled on boot with selinux=0

❯  sestatus               
SELinux status:                 disabled

It appears to work after sudo and fixing the error message regarding safe repositories with git.
