systemd-resolved was previously shipped in the systemd package, and
became a separate binary package during the kinetic cycle. This package
provides the default DNS resolver for Ubuntu, so we want it in ubuntu-
minimal.

Title:
systemd-resolved recommends libnss-resolve in kinetic, pulls it into
minimal system where it was explicitly excluded before
Status in systemd package in Ubuntu:
Triaged
Bug description:
In kinetic, systemd-resolved now Recommends: libnss-resolve, pulling
it into the ubuntu-minimal seed.
In the past we briefly had libnss-resolve seeded (between xenial and
bionic LTSes but not in any LTS) but it was removed because:
- it was redundant; /etc/resolv.conf was consistent and correct.
- its presence could mask wrong DNS configuration resulting in
difficult-to-debug differences in behavior between applications that did use
nss_resolved via /etc/nsswitch.conf and those that did not (examples: i386
binaries that could not use nss_resolved because it was not installed;
statically-linked go implementations that parsed /etc/resolve.conf directly and
did not load NSS modules)
This new recommends was noticed specifically because of some broken
kinetic container images where /etc/resolv.conf was broken (empty) and
*some* applications still worked via nss but others failed by trying
to use the DNS protocol directly. (I.e.: 2nd point above)
I believe systemd-resolved should drop its recommends on libnss-
resolve for Ubuntu.
