Hallo all!
I'm working on an embedded project consisting of an host and numerous virtual machines and am facing problems related to time management. systemd-timesyncd dies on one machine (HOST), but runs okay on another (VM2) with identical config.
The project setup is as follows:
HOST: Runs a (heavily) modified Debian with systemd, retrieves time via NTP from VM3 using systemd-timesyncd.
* VM1: Runs openwrt and serves time via NTP using chrony
* VM2: Runs a (heavily) modified Debian with SELINUX and systemd, retrieves time via NTP from VM3 using systemd-timesyncd
* VM3-?: Some other VMs which seem to run fine
The symptoms are as follows:
HOST: `systemd-timesyncd.service` is reported as inactive (dead). A time update (adjusting the time by 2 days) took place. Then, after 5min, the service died. (It always seems to die 5-15min after a time update.)
```
root@HOST:/var/log# systemctl status systemd-timesyncd

Looks like a normal exit, though. What systemd version is this? For v217 or later I'd expect to see _Status: "Shutting down"_...
Try starting it with [Service] Environment="SYSTEMD_LOG_LEVEL=debug" to see more details.
systemd-timesyncd configuration for both HOST and VM2
```
root@HOST, VM2:/var/log# cat /lib/systemd/system/systemd-networkd.service
That's not timesyncd...
