Do you search for DevOps or sysadmin in job postings?
Whether you want it or not, sysadmin is left to designate the low end of the market, namely desktops and windows administration work, sometimes all the way to helpesk. Devops simply evolved as a separate term to designate the higher end of the market around linux and automation.
Maybe in the silicon valley every company is a tech company looking for linux sysadmins and developers, but in the rest of the world "sysadmin" will usually get one into windows or low end roles.
I search for neither in job postings. Whatever the market wants to call it is fine, but that doesn't change the fact that at the end of the day we're just sysadmins with bigger hats and different titles. Even in San Diego, I see job postings for Systems Administrators and they are in fact just that, a sysadmin (sorry, "DevOps Engineer") and are not just for Windows or helpdesk work. The world outside of San Francisco is pretty normal, generally. Even my previous role at Sony was for a Linux Systems Administrator, but I still automated and did way more involved work than someone just doing printers and helpdesk.
