Verification done. First I downgraded all systemd packages to the release pocket using
# apt install '?installed?version(247.3-3ubuntu3.1$)=247.3-3ubuntu3' Then I hacked in Phased-Update-Percentage: 0 fields for all src:systemd packages in my local hirsute-updates Packages file in /var/lib/apt/lists using vim, resulting in # apt install libsystemd-dev Reading package lists...
