Systemd hang when restarting a service during shutdown

[Sean Nyekjaer <sean@xxxxxxxxxx>]

Hi,

Regarding,
https://github.com/systemd/systemd/issues/21203

I think the point of the issue missed when the issue got closed.

We have a service that is changing configs for systemd-networkd and
issuing a `systemctl restart systemd-networkd`.
An other service is checking uptime and issues a `systemctl reboot`,
when our max uptime have been exeeced.
If restart of systemd-networkd happens while a reboot is in progress,
the system will hang "forever" (and continue to pet the watchdog).
This is not a thing that eventually will timeout and reboot the
system...
