Hi all, this is a patch series for proper systemd integration. Main idea is to have the CLI socket controlled by systemd, so that the daemon will be started automatically if someone calls 'multipathd -kSomething'. The neat thing with this is that we can use the systemd-provided watchdog to detect stalls in checkerloop(), which always have been bitten us in the past and are really hard to diagnose remotely. Plus with socket activation we can now safely implement a 'one-shot' mode, where the daemon exits if no maps are discovered. Which means that we can enable the socket always, and don't have to worry about a daemon sitting in the background eating up resources and doing nothing. Oh. And some general fixes, too.
