Warnings during upgrades

[Richard Hector <richard@walnut.gen.nz>]

Hi all,

Sometimes, during an upgrade, I see a line like this:

Warning: The unit file, source configuration file or drop-ins of 
postgresql@15-main.service changed on disk. Run 'systemctl 
daemon-reload' to reload units.

Often, though, if there are lots of packages being upgraded, that will 
have scrolled off the top of my terminal.

Is it on me to scroll back and check for such things, or will that 
reload be triggered automatically when it happens during an upgrade?

I feel that it would be useful to either trigger the reload, or collect 
such warnings and redisplay them at the end.

Cheers,
Richard
