Hi,
Recently, I encountered a interesting phenomenon that CentOS 6.3 running as normal even if I (my colleague, actually) installed a kernel that build for CentOS 7.x (e.g. kernel-3.10.0-327.el7.x86_64.rpm).
I found kernel is mismatch accidentally when I using "uname -r" to check kernel version. So my question is what the harmness we will get if I install a el7 rpm into a el6 system?
Thanks.
