Title:
  systemd-sysctl crashes when there's a comment at the end of a line

Status in systemd package in Ubuntu:
  Won't Fix

Bug description:
  I have this line in /etc/sysrq.d/10-magic-sysrq.conf:

  kernel.sysrq = 1 #176

  This has worked in Ubuntu 14.04.

  Although there are errors and warnings, the setting seems to be
  applied on boot.
