Thank you very much, Jamie, for your detailed analysis in #15!
I've applied the same fix to isc-dhcp
https://launchpad.net/ubuntu/+source/isc-dhcp/4.4.1-2.3ubuntu3
We can consider SRUing this to Jammy and Impish, which are affect too.
But it doesn't feel too critical, as systemd-resolved usually wins the
race vs NetworkManager/dhclient, as you stated: "but with NetworkManager
as the netplan renderer, the dhclient script is called later and the dir
is created correctly."
I'm marking the systemd component as "Invalid", as the fix is needed in
other packages.

Bug description:
Running groovy on the desktop, with the systemd packages that migrated
today(/overnight EDT).
# Steps to reproduce:
1) `systemctl restart systemd-resolved.service`
(This is a minimal reproducer, but I first saw this after an apt
upgrade of systemd.)
# Expected behaviour:
DNS continues to work, status looks like this:
Link 2 (enp5s0)
Current Scopes: DNS
DefaultRoute setting: yes
LLMNR setting: yes
MulticastDNS setting: no
DNSOverTLS setting: no
DNSSEC setting: no
DNSSEC supported: no
Current DNS Server: 192.168.1.1
DNS Servers: 192.168.1.1
DNS Domain: ~.
lan
# Actual behaviour:
DNS is unconfigured:
Link 2 (enp5s0)
Current Scopes: none
DefaultRoute setting: no
LLMNR setting: yes
MulticastDNS setting: no
DNSOverTLS setting: no
DNSSEC setting: no
DNSSEC supported: no
# Workaround
Disconnecting and reconnecting my network connection restored DNS
functionality.
