During the unattended deployment process I want the client to perform a local boot. If I just reboot the client it restarts the installation because Foreman does not know about the reason and delivers the same old boot file. If I wget the built-URL the client state switches to successfully installed and the client does the local boot. The problem is that the installation process is still running and might go south. That leads to a dysfunctional client that looks green and good in Foreman.

I think something like foreman_url('continue_local'), that switches the state to local boot, but installation still running would help. In a subsequent step the client then can signal the successful completion of the installation process with wgetting the built-URL.
