Adds a fast, reproducible install path that unpacks a prebuilt AlmaLinux 9 node
rootfs onto the device (Anaconda liveimg) instead of resolving packages, with
per-host networking still templated after the unpack. Reuses the OptiPlex storage
vars so image and package installs lay disks out identically. Templates-only per
review; the rootfs build lives in the bootapi-images repo.
- kickstart/image.ks.tmpl: liveimg --url={{ .DistroVars.rootfs_tarball }};
%post renders per-host NetworkManager keyfiles from NetBox interface data
(the image is generic and liveimg overwrites /etc), hostname, puppet-initial
PUPPETCA_URL env, and the provisioned callback.
- kickstart/_storage.ks.tmpl: shared storage-block/storage-pre partials
(storage_mode / vg_grow); almalinux9.ks.tmpl now uses them (no behaviour
change).
- catalog/almalinux9-image.yaml (VM autopart) + optiplex-7080-image.yaml
(auto-nvme + vg_grow), rootfs_tarball -> artifactapi rootfs-images repo.
Rootfs tarball built+published by https://git.unkin.net/unkin/bootapi-images
(v* tag). Validated with bootapi validate + shellcheck; no bootapi code change.

AlmaLinux 9 kickstart (package install), ported from the Cobbler default.ks
|
|
contract. Install source is the artifactapi almalinux remote (catalog mirror
|
|
var). The %post installs the Puppet agent, points it at the k8s puppetserver,
|
|
writes the puppet-initial PUPPETCA_URL env file, then posts back to bootapi so
|
|
pxe_enabled flips off (Cobbler's netboot_enabled flow).
|
|
|
|
Storage is model-aware via the shared _storage.ks.tmpl partials (storage_mode /
|
|
vg_grow catalog vars) so this and image.ks.tmpl lay disks out identically.
|
|
|
|
Data model: docs/data-model.md. `.RootPasswordHash` / `.ProvisionToken` come
|
|
from Vault/env at render time, never from NetBox.
