CHANGELOG

2025:12-07 - Tiny Cloud v3.2.3

Correctly identify empty user-data content instead of flagging it as "unknown".

Fix Makefile to dynamically generate the list of clouds, allowing the new code for DigitalOcean (and future additional clouds) to also be installed.
Fix testing with oksh.

Fix cloud-config user creation -- users would reuse values from previous user if unset.

Default to "/usr merge" friendly installation locations
Configure cloud provider via kernel cmdline or DMI system serial -- either with or tinycloud=cloud=<cloud> (we may introduce additional cmdline Tiny Cloud config settings in the future) or ds=<cloud>.
Autodetection of aws, azure, gcp, hetzner, oci, and (maybe) scaleway cloud providers via DMI information.
Current order of priority for determining cloud...
- /etc/tiny-cloud.conf (image hardcoded)
- /var/lib/cloud/.autodetect (previously detected)
- /proc/cmdline (tinycloud=cloud=... or ds=...)
- /sys/class/dmi/id/product_serial (QEMU hack, same cmdline)
- /usr/lib/tiny-cloud/cloud/*/autodetect scripts
Makefile improvements
- generalize cloud install targets
- ensure all user-data handlers get installed

Officially add Makefile targets and flesh out tests for newer cloud modules: hetzner (@hmrodrigues), incus (@ncopa), and scaleway (@hmrodrigues).
cloud-config user-data handler has been fleshed out with a subset of functionality, allowing the use of some common #cloud-config user-data configuration.
alpine-config user-data handler has been reimplemented as an extension of cloud-config, adding management of APK repositories and Alpine autoinstall.
Remove deprecated hotplug modules. nvme-ebs-symlinks has been deprecated since v3.0.0, and imds-net-sync hasn't been supported for AWS since tiny-cloud-network-2.2.2-r0 in Alpine Linux 3.17.
Remove code related to the installation/testing of hotplug modules.

Replace non-functioning tiny-cloud --setup with working --enable and --disable to enable/disable the set of Tiny Cloud init scripts.
Reload user-data if bootstrap is incomplete, even if previous user-data file exists.
Init actions that fail should cause tiny-cloud to also terminate with an error.

Adds support for additional ssh-authorized-keys via userdata for experimental Alpine auto installer.

Tiny Cloud has been reorganized into four init script phases...
- boot - "boot" runlevel, after syslogd is started, and before networking is up.
- early - "default" runlevel, after networking is up, but before user-data is made available. This phase is responsible for pulling in user-data for later phases.
- main - "default" runlevel, after user-data is available. Most things get done here.
- final - "default" runlevel, after all other init scripts have finished. Typically user-data scripts are run here, and bootstrap status is marked as complete.
Tiny Cloud init functionality has been consolidated into /sbin/tiny-cloud and init scripts should use tiny-cloud <phase> to indicate whether boot, early, main, or final actions should be taken.
Use tiny-cloud --setup to add/update Tiny Cloud's init scripts into the right runlevels. Currently only OpenRC is supported.
The example OpenRC init scripts been updated and moved to dist/openrc/.

Tiny Cloud now supports the concept of user-data handlers, to support acting on different payload content-types.
Clouds and user-data handlers can specify their own (or supercede the default) init functions and/or change the init phase in which they are executed. The order of declaration is default --> cloud --> user-data (last one wins).
We now have an experimental alpine installer "cloud", based on NoCloud, and an associated #alpine-config user-data handler, which supports a subset of #cloud-config features, plus some extensions. As this is new, we expect it to experience some continued evolution.
Also thanks to Nataniel Copa (@ncopa), Tiny Cloud now has unit tests.

nvme-ebs-symlinks has been deprecated and disabled by default. The mdev-conf package, as of v4.4 is now responsible for maintaining NVMe device symlinks for AWS.

WARNING: The behavior of mdev-conf is slightly different -- either /dev/sd or /dev/xvd symlinks are created as indicated in NVMe device metadata, but NOT both!

Tiny Cloud configuration has moved to /etc/tiny-cloud.conf.
imds now supports @local-hostname alias. For most clouds this is the same as @hostname.
Fixed setting local-hostname metadata from /proc/cmdline for NoCloud.
