"killing" is very UNIX terminology, and not really what this is about.
Let's be more correct and say "send a UNIX signal" for the operation.
Otherwise things are really weird if users call "journalctl --rotate"
from the command line, which internally asks systemd to send SIGUSR2 to
to journald: when german locale is selected this asks the user — roughly
transliterated — whether they want to "eliminate" journald, which is
definitely not the intended meaning.
