This may seem like a ridiculous comment but I love that a lot of work on Linux has been to make it easy-as-pie to install/setup quickly and I feel like it's happened in the last couple years (cgroup + systemd stuff mostly). I praise docker for making immutable services commonplace, but I also love projects like cockpit from redhat + netbox + coreOS. There used to be so much technical debt that went into getting a server off the ground and monitoring it.

I'm weird, dunno if others agree ~
