# No upgrade here on purpose. `apt-get upgrade` holds back packages that need
# new dependencies, which produced pve-cluster 9.1.6 against
# libpve-cluster-api-perl 9.1.0 — a combination no real install ever has, and
# one whose cluster join silently leaves the node unclustered. The ISO is the
# pin; the currency lane is where upgrades get exercised.
