For me, my high bar that I have yet to beat, was the time I pivoted the running OS (ubuntu) into RAM over SSH so I could unmount and image the boot drive without rebooting and loading a live USB (Which would have required a ticket with my provider to enable IPMI)
With Linux I’m so used to having all the control nothing really feels like magic. My entire desktop environment is controlled by set of custom lua scripts. Every detail looks and works exactly the way I set it up to. But it’s not magic, it’s just Linux.
