I prefer ifupdown, but I like Network Manager for laptops. This particular
behaviour can be managed, which is useful for me given that I have various
ways I need to manage resolv.conf on different systems.
For what it's worth, here's an excerpt from the NetworkManager.conf(5) man
page - take special note of the last paragraph:
dns
Set the DNS (resolv.conf) processing mode. If the key is
unspecified, default is used, unless /etc/resolv.conf is a symlink
to /run/systemd/resolve/stub-resolv.conf,
/run/systemd/resolve/resolv.conf, /lib/systemd/resolv.conf or
/usr/lib/systemd/resolv.conf. In that case, systemd-resolved is
chosen automatically.
default: NetworkManager will update /etc/resolv.conf to reflect the
nameservers provided by currently active connections.
dnsmasq: NetworkManager will run dnsmasq as a local caching
nameserver, using a "split DNS" configuration if you are connected
to a VPN, and then update resolv.conf to point to the local
nameserver. It is possible to pass custom options to the dnsmasq
instance by adding them to files in the
"/etc/NetworkManager/dnsmasq.d/" directory. Note that when multiple
upstream servers are available, dnsmasq will initially contact them
in parallel and then use the fastest to respond, probing again
other servers after some time. This behavior can be modified
passing the 'all-servers' or 'strict-order' options to dnsmasq (see
the manual page for more details).
unbound: NetworkManager will talk to unbound and dnssec-triggerd,
providing a "split DNS" configuration with DNSSEC support.
/etc/resolv.conf will be managed by dnssec-trigger daemon.
systemd-resolved: NetworkManager will push the DNS configuration to
systemd-resolved
none: NetworkManager will not modify resolv.conf. This implies
rc-manager unmanaged
