At least unattended-upgrades from Debian/Ubuntu/... can be configured to install updates on shutdown (without any special mode or something). And, yes, this can run for more than 30 minutes, which I could already observe in its default mode (installing during normal system activities), so I see no reason why this should not happen when configured to install during shutdown. The reason is, that unattended-upgrades can basically update the whole distribution to the next version, which naturally can take a lot of time.
It's questionable if this is a sane setup, but I can think of setups where this might be useful, e.g. having two identically configured servers for redundancy reasons where one server would be enough. Then it might make sense to update one system during shutdown while the other one takes over. This has the advantage, that normally running servers either have the old or the new state, but never some intermediate state during the update. The shutdown time does not really matter in this case and a watchdog killing the system wouldn't be welcome. But all in all this seems like an exotic use case. Kind regards Patrick
