[arch-general] systemctl daemon-reexec - anything else needed after systemd update?

You might be interested in what running process have deleted files still
open, perhaps because a package upgrade has installed a new version, or
caused a updated version to be generated.  A quickly knocked together
pipeline I use is

    sudo -i lsof -n +c0 |
    sed -n '1{p;d}; /DEL/{p;d}; / (deleted)$/{p;d}' |
    egrep -v ' /(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}'

Not all the entries it shows matter, of course.  It's up to the reader
to parse and, say, decide to restart postfix.
