IIRC, some other distros re-start a server as part of the package-upgrade process, including if a configuration file or a dynamically-loaded library used by the server from another package has been re-written. It was a surprise to me on moving to Arch that it didn't. I've a little ~/bin/oldpkg which I run after an Arch upgrade to help eyeball those servers which are using now-deleted files which I think have been replaced during the upgrade. sudo lsof -n +c0 | sed -n '1{p;d}; /DEL/{p;d}; / (deleted)$/{p;d}' | egrep -v ' /(run/systemd/(inhibit|sessions)/[0-9]+\.ref|SYSV00000000|dev/shm/org\.(chromium\.......|mozilla\.ipc\.[0-9]+\.[0-9]+)|memfd:pulseaudio|tmp/#[0-9]{5,7})\>' | sed '1{h; d}; 2{x; G}' -- Cheers, Ralph.
