From d6993d35368f4733cac7dfd23be354de7ef0a0fb Mon Sep 17 00:00:00 2001 From: Craig Jennings Date: Wed, 8 Jul 2026 05:45:51 -0500 Subject: test(maint): add VM and nspawn remedy scenario harness Nine break/fix/assert scenarios run the real maint fix inside the test VM. The runner batches non-conflicting scenarios into one VM boot, restores the snapshot only between groups, and leaves the base image pristine afterwards. A systemd-nspawn fast lane runs the pacman-level group against a cached pacstrap rootfs in seconds. The plan layer validates the scenario contract without a VM and carries a 19-test unit suite. make test-maint wires the VM lane in. The zfs lane is filtered but unexercised: the FS_PROFILE=zfs base image fails to build (ZFS DKMS module not found on linux-lts 6.18). The failure is tracked in the todo. --- scripts/testing/maint-scenarios/20-cache-keep3.sh | 24 +++++++++++++++++++++++ 1 file changed, 24 insertions(+) create mode 100644 scripts/testing/maint-scenarios/20-cache-keep3.sh (limited to 'scripts/testing/maint-scenarios/20-cache-keep3.sh') diff --git a/scripts/testing/maint-scenarios/20-cache-keep3.sh b/scripts/testing/maint-scenarios/20-cache-keep3.sh new file mode 100644 index 0000000..a9a6ee5 --- /dev/null +++ b/scripts/testing/maint-scenarios/20-cache-keep3.sh @@ -0,0 +1,24 @@ +# shellcheck shell=bash disable=SC2034 # sourced by run-maint-scenarios.sh +# Scenario: paccache -rk3 trims an installed package's cache to 3 versions. +# +# paccache decides from filenames, so five fake versions of a package that +# IS installed (bash) stand in for a fat cache.
