What were you trying to do that didn't work?

I installed the wireguard-tools package. After that, DNS was broken.

The reason is that wireguard-tools depends on systemd-resolved (which isn't installed by default in CentOS 10). Installing systemd-resolved changes the static /etc/resolv.conf to a symlink to ../run/systemd/resolve/stub-resolv.conf , but doesn't actually start the service.

Please provide the package NVR for which bug is seen:

systemd-resolved-255.3-1.el10.x86_64

How reproducible:

Always

Steps to reproduce

dnf install -y wireguard-tools
ping google.com

Expected results

ping (or any other network operation) works.

Installing systemd-resolved should either start the service by default, or not change resolv.conf – changing the symlink could be moved to the unit start?

Actual results

"ping: google.com: Temporary failure in name resolution"

This also breaks subsequent dnf install and everything else web-y.
