Description:
I have tried to import the official Arch Linux cloud image from https://mirror.pkgbuild.com/images/v20211201.40458/Arch-Linux-x86_64-cloudimg-20211201.40458.qcow2 into Microsoft Azure. The steps taken (based on https://docs.microsoft.com/en-us/azure/virtual-machines/linux/create-upload-generic) were: * Convert the image to fixed-vhd format * Create a storage account * Upload the image * Create a disk from it * Create a VM from this disk * Provide the following cloud-config: ``` #cloud-config fqdn: archlinux-on-azure users: - name: user sudo: "ALL=(ALL) NOPASSWD: ALL" ssh_authorized_keys: - "ssh-ed25519 AAAA... my-ssh-key" shell: "/bin/bash" ``` Result: cloud-init failed to run in the resulting Azure VM, because it could not execute the "hostname" command to set the host name. The log (extracted by attaching the disk to a different instance) is attached. Fixing up the image by installing inetutils was sufficient for cloud-init to run successfully. Conclusion: cloud-init must have a dependency on inetutils, because this is the package that provides the "hostname" program, without which cloud-init does not run at all on Azure and does not continue e.g. provisioning user accounts. I have tried to reproduce this locally without Azure, using the "nocloud" data source, but it appears that cloud-init can set the hostname without calling "hostanme" in this case. So the bug is Azure-specific, and you can find explicit references to the "hostname" command if you look into /usr/lib/python3.9/site-packages/cloudinit/sources/DataSourceAzure.py .

Hm, I was under the impression that this has been finally fixed upstream (by wCPO) and relies on systemd's hostnamectl if hostname is not available.

I confirm that it works on Azure unmodified (other than format-conversion via qemu-img).
