[systemd-devel] systemd-tmpfiles, unsafe path transitions

I am doing dev work on a linux system and I am mounting the root filesystem via NFS to make my work-flow easier.

Unfortunately, the directory I am NFS mounting is not owned by root, and this causes some of the directives processed by the systemd-tmpfiles utility during boot (e.g. in systemd-tmpfiles-setup.service) to fail due to unsafe path transitions:

    Detected unsafe path transition / (owned by <numeric-id>) -> /run (owned by root) during canonicalization of run/log/…

Is there a conf option or an environment variable I can use to disable the unsafe path transition check?

Failing that, is there a way I can change the ownership systemd-tmpfiles sees?

Thanks,

-James M
