From a5aecd484ff7fd7215e57c7d3b4448d2b68367f0 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 01/11] 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.

Archives up to 16 MiB come back base64 encoded, larger ones stay in /var/lib/support, as does the log of a failed run, until a later call prunes them after a week. nacm:default-deny-all like install-bundle, the archive carries logs and the full configuration. The abort event sysrepo sends after a caller timeout is ignored, it used to run the collection twice.
