whenever a new jenkins package is available and installed by apt-get install or unattended-upgrade, jenkins is immediately re-started. This is very intrusive because it immediately cancels running users jobs. This is especially annoying on long-running jobs over night.

Package upgrades should not impact users processes. Fortunately jenkins has the option to re-start as soon as it is idle.

when installing an upgrade that should be used instead of the immediate re-start.
