Interactive shell script for keeping a CentOS 7 (or any yum package system linux build for that matter) test build at latest and printing yum list output in a loop.
This will reboot your machine for the first run if you don't use the install script first.
When it detects a kernel version change, rolling-saturn reboots the system.
Also, the first time it is run, it will reboot the machine unless the following is done (via install script):
yum list installed | grep "kernel[.]" > /root/yum.before
That way the first run has something to compare to!
