Subject: [PATCH 5/8] gen_hosts: scope the python interpreter per inventory group
Date: Thu, 23 Apr 2026 00:16:46 +0200	[thread overview]
Message-ID: <20260423-kdevops-series-a-fixes-v1-5-69a82d0e1631@samsung.com> (raw)
In-Reply-To: <20260423-kdevops-series-a-fixes-v1-0-69a82d0e1631@samsung.com>

From: Daniel Gomez <da.gomez@samsung.com>

Every inventory group's :vars scope emitted a single
kdevops_python_interpreter defaulting to /usr/bin/python3, so
selecting the NIXOS backend left every guest trying to run
Ansible modules through a path that does not exist on NixOS
(/run/current-system/sw/bin/python3 is the correct one).
Overriding the variable globally would break the control node,
which on most kdevops hosts is a Debian box with no NixOS paths.

Split the interpreter into per-group Kconfig strings with
output yaml: baseline, dev and service each default to the NixOS
path under NIXOS and fall back to kdevops_python_interpreter
otherwise. Localhost stays under [all] and keeps the control-node
interpreter; guests pick the backend-appropriate one by inventory
group.

Fixes: 3089c3fec57 ("nixos: add NixOS support as third bringup option with libvirt integration")
