Thanks for all the clarifications MB.

received any commit this year. The development may now happen elsewhere (or
not).
I wouldn't be surprised if the development on systembsd is stalled. For me
re-implementing this API in a portable way is a full time work with a new
release to support every two months + the fact that wasn't intended to be
used outside Linux. So ideally systemd should be design for potability to
other free *nix kernels.
