I am trying to find out what version of CentOS is running at a
customer site, but I do not have remote access and there is no one
there to run anything for me. But I do have a dmesg output and I see

Linux version 3.10.0-327.22.2.el7.x86_64
(builder at kbuilder.dev.centos.org) (gcc version 4.8.3 20140911 (Red Hat
4.8.3-9) (GCC) ) #1 SMP Thu Jun 23 17:05:11 UTC 2016

>From that can someone tell me what the CentOS version is?
