nsswitch appears to be "modified manually"

[biva]

Describe the bug

I installed Wireguard, it works well. But now I see this message in the diagnostic of Yunohost:

Configuration file /etc/nsswitch.conf appears to have been manually modified. This is probably OK if you know what you're doing! YunoHost will stop updating this file automatically... But beware that YunoHost upgrades could contain important recommended changes. If you want to, you can inspect the differences with yunohost tools regen-conf nsswitch --dry-run --with-diff and force the reset to the recommended configuration with yunohost tools regen-conf nsswitch --force

I ran the command to inspect the differences:

Warning: The configuration file '/etc/nsswitch.conf' has been manually modified and will not be updated

I'm not sure if wireguard installation did it, but the timestamp corresponds. Is it normal? Is there a way to avoid that?

I read in https://forum.yunohost.org/t/warning-pour-fichier-de-configuration-etc-nsswitch-conf-modifie-manuellement/18244 that @alexAubin says that we can restore the original file without stress, is it the case here?

That is unrelated to the WireGuard package. :) You are safe to follow the instructions from the forum.
