Support disabling systemd notification integration at run time. In some deployments of mulitpathd, systemd is ultimately used but not in stage-1 of boot. In this scenario multipathd is used to mount the root volume, and then switch_root runs, and we call systemd. For this use case it is possible to "just" have two copies of multipathd around, one with and one without systemd support, but it is a bit tricky and annoying to juggle the two.

What's the problem you're trying to solve? I'd expect if systemd isn't running, you'd just see some error messages about undelivered notifications. Or does multipathd indeed hang? |

Thanks for the prompting. I think we convinced ourselves the systemd integration was breaking our system and went as far as writing this patch. However, when I don't apply this patch to our known-to-work environment it isn't needed. Sorry for the noise :). |
