[systemd-devel] systemd link file rename eth0 do not take effect

[He, Guocai (CN)]

All:

Thank you for all your reply and the useful advice.

There is progress on this issue

In logs I find this:
Jun 17 02:46:02 intel-x86-64 systemd-udevd[252]: Skipping overridden file '/lib/udev/rules.d/80-net-setup-link.rules'.

So I find:
root at intel-x86-64:~# ls -l /etc/udev/rules.d/80-net-setup-link.rules
lrwxrwxrwx 1 root root 9 Mar  9  2018   /etc/udev/rules.d/80-net-setup-link.rules -> /dev/null

I remove the file and it works.

I don't know why and where this file /etc/udev/rules.d/80-net-setup-link.rules from.

Thanks,
Guocai

Why? NamePolicy is empty by default and only one .link file is applied.
There should be nothing to clear unless I miss something.

And any drop-in is processed after the file itself so it is impossible
to clear settings in drop-ins, correct?
