I doubt it's increasing robustness for any existing application as
pid_traditionally was 16 bit. I don't know if some applications try to
sprintf() a pid into a char[6], but if they do, it might cause an application
failure...

Now you know one ;-)

I still wonder why systemd has to mess with all these kernel variables BY
DEFAULT.


...

I think systemd is too complex already, and it's getting more complex every
release. I don't like those attempts to build another operating system in the
init process, but your opinions may vary.
