name: Test Patches - Weekly

# Weekly regression test of pve-mod against the latest upstream Proxmox VE files.
# Mods are auto-discovered from the [modules] section of src/pve-mod.conf and
# tested in parallel - adding a mod needs no change here. If a mod fails, an
# issue is opened (or updated) per failed mod explaining why.
