Added both cloud-ini t and init-system-helpers from proposed to the standard Xenial cloud image (com.ubuntu.cloud:released:download/com.ubuntu.cloud:server:16.04:amd64/20160907.1/disk1.img) on a suitably sized server.

Rebuilt a new server from the snapshotted image using the previously failing postgresql user data and all is well. The new packages correct my problem - bug 1611973 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1576692 Title: fully support package installation in systemd To manage notifications about this bug go to: https://bugs.launchpad.net/cloud-init/+bug/1576692/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
