Are you trying a joke on Linux vs Unix? in reference to companies using Solaris or FreeBSD maybe? (there aren't many left of those).
All the DevOps roles I've ever seen are Unix based. In my experience sysadmin roles were more likely to be a windows administration or a helpdesk role than that.
I think it's pretty good devops got split into a distinct title. It's not a great experience walking into a sysadmin interview only to find out they are looking for an exchange administrator.
No, I'm saying the the DevOps ideas have nothing to do with OS choice. You could use them in linux or Windows or in any other OS; or you could ignore them in linux or Windows or any other OS.
