EDIT: I just noticed this thread is pretty old. Sorry for digging it up.
I need to say that I don't know exactly what systemd is doing as I am just getting into Linux and frankly don't know the alternatives, but systemd is doing really good where ever it's mentioned in documentary.
I am also a fan of systemd-boot which is straight forward and easy to maintain my entries unlike GRUB2 where I messed up greatly and it refused to boot my x64 OS in UEFI. Not as beginner friendly as systemd in my opinion.
