[Unit]
Description=Rebuild the w3cs CRIU claim image matrix when its fingerprint changed
# Runs after the daily unattended upgrade window (06:00 + up to 1 h random
# delay). A rebuild is a no-op unless the fingerprint changed; when it did
# (engine, proxy, wine, or a system library), seats are rebuilt serially and
# restarted, so run it in the quiet morning window.
