From d9568085f2502ee4f0f3bf17846a32c4e67de7bb Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Mattias=20Walstr=C3=B6m?= Date: Thu, 17 Sep 2026 09:35:14 +0200 Subject: [PATCH 01/16] support: break out into its own package, add option for gpg MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The support script was installed by the bin package, and its -p option relied on gpg being in the image only as a side effect of podman pulling in libgpgme. Give it a package of its own with an encrypt option that selects gnupg2, enabled in all non-minimal defconfigs, so the dependency is explicit. The WebUI calls the tool, so it selects the package.
