I've CCed NetworkManager maintainers: since here /etc/resolv.conf is a
symlink created by NetworkManager, perhaps they can provide some advice.
Regarding the opening message, I've workarounded the problem overriding
the squid service like this:
# systemctl edit squid.service
---------------
[Unit]
After=network-online.target
---------------
But that didn't work with my PC at work (see message #30), for which the
override had no effect. Perhaps there the problem has different origin:
I have to investigate better on this.
