Container Linux should phone-home to Packet on boot failure

[crawford]

Issue Report

Feature Request

Environment

Packet.net

Desired Feature

When Ignition is fed a bad config, it prevents the boot from succeeding. As a result, the packet-phone-home.service doesn't run, which leaves the machine in a failed provisioning state (Packet then removes the machine from the available pool). Instead, packet-phone-home.service should be run from the initramfs when Ignition fails. This will allow Packet to continue using that machine and the user to get a console and debug.

Other Information

It would be nice if the API allowed us to indicate a boot failure, but I don't believe it supports that yet.

See also #2042, which is slightly different.

This will require adding curl (or equivalent) to the initramfs.
