CentOS 7.5 doesn't support SysVinit.
I have used CentOS since version 6.0 (2011)
And have the most practice on this OS than any other UNIX like OS.
On my /54 node station, I use Debian 9.x. because CentOS 7.x doesn't support 
i686 platform.
My hardware based on two Pentium-III CPUs. In this OS default autorun is 
systemd. In our region we haven't modern hardware and enough money to buy it. 
I prefer a binary long support Linux OS.
Can you suggest anything else?
