Usage differences between CentOS 6 & 7

[Tornation]

Due to this bug related to j1900 boards I can't install CentOS 7. However from my very limited testing CentOS 6 installs properly. Recently (before I tried to install either), I took a course on lynda.com for administering a CentOS 7 machine. Are there any major usage differences that would stop current knowledge of CentOS 7 from applying to CentOS 6. (Note: I am almost completely controlling it via ssh. no desktop)

Well, the biggest and most significant difference between CentOS (and RHEL) 7 vs previous versions is the surrendering to systemd over init.  Version 7 is "all in" with systemd; init is gone.  That means that all of the start-up scripts that init uses are gone (/etc/rc.d/init.d), etc.  So going back to v6 means you'll be back in the init playground, which is more in line with historical UNIX-like OSs.

 

Outside of that, UNIX is UNIX, Linux is Linux.  If you can drive one version, you can drive any of them.

Thank you!
