I'm running Debian 8 x64 and still learning it. One of the confusing things I've come across repeatedly on Debian and Ubuntu systems is there appear to be two ways of running and managing services:servicesystemctlI've read through the Debian page on systemd (systemctl) as well as questions such as How does systemd use /etc/init.d scripts?From what I understand so far, many Linux distributions these days, including Debian and Ubuntu, are moving away from the old SysV (System Five) and embracing systemd.I can see that my /sbin/init is a symbolic link to /lib/systemd/systemd.The question is:If systemd has replaced SysV, why is SysV (service) still there?Why can I use both seemingly interchangeably? If I start a daemon in one, the other knows about it. How? Which one is running the show?Is there any real reason to use service any more or should I just stick to systemctl?
If systemd has replaced SystemV, why is it still there and who is running the show?
