Hi Tim, The change in the unit file seems legitimate, and the USE_SYSTEMD build option is fine, however I think we can improve slighly the patch.
I think a good way to activate this feature will be to use it with a -Ws command line option instead of changing the behavior of the -W one. This way we can integrate the -Ws command in the unit file without changing the behavior of the normal option. Cheers, -- William Lallemand
