RLIM_INFINITY is defined as ~0ULL, at least on my system. If it's cast to a signed value, that will come out at -1, no?
My problem with systemd isn't that it doesn't work, it's that it's all-pervasive and viral, and forces people who've been using standard unix mechanisms for 20 years to learn something completely different for no visible concrete advantage. As a user rather than a sysadmin it seems I have to spend most of my time learning new ways to do exactly the same things without gaining anything. Frankly I'm past the point where I want to fiddle with Linux for hours to make it do what I want. But that seems to be the Linux Way these days, see eg ip vs ifconfig, iptables vs ipchains, &c &c &c.
