    It's so much easier to debug a boot dependency issue now thanks to ! Who wouldn't want such a nice graph ('systemd-analyze --order|dot -Tsvg' that took 2 min to gen) instead of 'ls /etc/rc3.d/' please give me the force...

    Pure C functions cannot throw exceptions. However, C functions (specifically, with extern "C" linkage) called from C++ are not implicitly noexcept, so the compiler will have to treat them as if they may throw. So C functions included into C++ will often generate non-ideal code.
