I am having some troubles in making systemd-resolved to properly work. My configuration is "minimal": the main configuration file /etc/systemd/resolved.conf is basically empty (everything is commented out) and I've a very simple drop-in file in /etc/systemd/resolved.conf.d/99-default.conf configuring a couple of (global) name servers.
The configuration is synthesized by the following output:
root@host:~# systemd-analyze cat-config systemd/resolved.conf
# /etc/systemd/resolved.conf
# This file is part of systemd.

# Entries in this file show the compile time defaults. Local configuration

The problem is that the drop-in file seems to be completely ignored at runtime... I mean if a trigger a command for summarizing the systemd-resolved status then the output is the following:
root@host:~# systemd-resolve --status
Global
Protocols: -LLMNR -mDNS -DNSOverTLS DNSSEC=no/unsupported
resolv.conf mode: uplink
Fallback DNS Servers: 1.1.1.1#cloudflare-dns.com 8.8.8.8#dns.google 1.0.0.1#cloudflare-dns.com 8.8.4.4#dns.google 2606:4700:4700::1111#cloudflare-dns.com 2001:4860:4860::8888#dns.google
2606:4700:4700::1001#cloudflare-dns.com 2001:4860:4860::8844#dns.google
Link 2 (wired1)
Current Scopes: none
Protocols: -DefaultRoute -LLMNR -mDNS -DNSOverTLS DNSSEC=no/unsupported
Link 3 (wired0)
Current Scopes: none
Protocols: -DefaultRoute -LLMNR -mDNS -DNSOverTLS DNSSEC=no/unsupported
I was expecting to find the DNS servers specified in drop-in file (192.168.2.105 and 192.168.2.106) in Global section of the output... but they are not there...
What am I mistaking? Is there something I am completely missing out? (that's very likely, since I am a systemd-resolved beginner)
