[systemd-devel] issue of failing to start Network Name Resolution

[Cranegsh]

Hello,

I am setting up the wifi for a customized Linux image. It uses systemd to
manage the network.

Right now, I am able to config the ip address and ping 8.8.8.8, but get
"bad address" when ping google.ca.

It is because the systemd-resolved service failed to start.

systemctl status shows below info:
Active: failed (Result: exit-code)
Process: 254 ExecStart=/lib/systemd/systemd-resolved (code=exited,
status=226/NAMESPACE).
Main PID: 255 (code=exited, status=226/NAMESPACE)

journalctl shows below info:
systemd-resolved.service: Failed to set up mount namespacing:
/run/systemd/unit-root/dev: No such file or directory
systemd-resolved.service: Failed at step NAMESPACE spawning
/lib/systemd/systemd-resolved: No such file or directory

I guess the issue is that the files required for systemd-resolved to
execute successfully are not there.

But by googling I couldn't find how to set up these two files and how
systemd-resolved sets up the name server.

Has tried to configure the name server in /etc/systemd/resolved.conf,
/etc/systemd/resolved.conf.d/dns.conf and /run/systemd/resolve/resolv.conf.
Or add DNS=xxx in /etc/systemd/network/20-wireless-dynamic.network. None of
them work.

I am wondering if something is missing there or if any debugging methods
can be used. Thanks!

Regards,
Crane
