thanks, @bgilbert.

I tried again on the t1.small.x86 device plan with an http rootfs URL in the iPXE configuration. I was able to successfully authenticate using ssh core@... after installation completed and the node rebooted into a blank SOS (serial console) screen. 🎉

(SSH keys were configured in the example.ign file included above, which was generated with these examples https://docs.fedoraproject.org/en-US/fedora-coreos/authentication/#_using_an_ssh_key and an FCCT to IGN conversion https://coreos.github.io/fcct/getting-started/#getting-fcct.

The Equinix Metal API accepts ignition files in userdata, which is how I've been supplying this:

packet device create --userdata-file example.ign --hostname mj-rhcos-heal-the-world --plan t1.small.x86 -p $PROJECT_ID  -t "rhcos,ipxe,testing,openshift-ipi" -i https://gist.githubusercontent.com/displague/5282172449a83c7b83821f8f8333a072/raw/f7300a5ab652e923dddacb5c9f206864c4c2aceb/rhcos.ipxe    --operating-system custom_ipxe --facility any -T "$(TZ=UTC date -v+1H +"%Y-%m-%dT%H:%M:%SZ")"

---

The /dev/sda vs /dev/sdb problems on t3.small.x86 is something I'll have to check on later. I'm really surprised to find that configuration.

Noting that I have a similar gist open for CentOS Stream https://gist.github.com/displague/cd5938eb7584dd1c1cc76c28a3f9c762
