I Sysadmin in education here in Brisbane. Half our server stack is Linux on a Nutanix hypervisor. I do all my work from Linux, my junior admin recently moved his workstation to Fedora KDE, I use Kinoite.
The student and staff devices are 95% Windows, manager doesn't care what we use to administer. Officially we're a "Microsoft School"
I just build what they need, networks, auth, security etc -I'll leave teaching to the teachers
