I’ve been using CentOS since versions 4.x, and I see a weird trend in recent Linux distributions.
Under CentOS 4.x, 5.x and 6.x, shutting down a server (workstation, laptop) simply meant issuing ‘shutdown -h now’ (or choosing ‘Shutdown’
from the GUI menu), and the machine would simply shut down. Whatever crazy process went haywire, shutting down the system meant exactly that. No questions asked.
Now with CentOS 7.x, sometimes the machine would simply hang during the shutdown process, or I would get a message like “a stop job is running”, and I would end up having to hit the Reset button to stop the system, as I did when I used Microsoft Windows (before 2001).
