Sysadmin is a System Administrator, which performs operations manually.
For decades before DevOps was coined, Sysadmins were automating infrastructures with tools like Kickstart, Jumpstart, CFEngine, ISconf, Rancid, netboot/pxeboot/dhcp, etc. I first provisioned infrastructure with CFEngine in 1996 or 1997.
So, you did DevOps work in 1996, long before the DevOps term was coined.
Creating a tools, that allows us doing a simple, repeatable and - usually - automated tasks, always was an important part of sysadm role. Of course, there were ones that did everything manually and wasn't able to write own code: we called them "operators".
From my point of view: "devop is that hasty one, that doesn't care about long-term support of underlying infrastructure".
Yep.

SecOps = sysadmin has to apply the CIS/SCAP/whatever security template to the machine
DevSecOps = developer also has to apply the CIS/SCAP/whatever security template to their machine
It all ends up becoming marketing jargon for suits looking to follow the next big trend.
