You have wanted to try Linux for years, and you quit in the same place every time: the install, the hotkeys, and all the ways to break the thing before you have done anything with it. After 20 years deep in Windows internals and three on a Mac, Sash hit exactly that wall, then installed Omarchy, DHH's Arch and Hyprland desktop, on a dusty Lenovo ThinkCentre off the SD card in his Sony a6000, because no USB stick in the house held six gigs. It installed in under five minutes. The first thing he did was open Codex inside it.

Omarchy ships nine agent CLIs pre-wired, Claude Code, Codex and Hermes among them, and a hotkey that launches whichever one you make the default. From there every change started as a sentence. Codex taught him the tiling hotkeys in about 20 minutes by moving the windows itself, built an app launcher bar in five, named his workspaces (Build, Comms, Studio, OS, Flex), and embedded a four-time-zone world clock in the bar. Asked what it knew about the system, it surfaced the agent skills Omarchy installs on disk: manuals for building plugins and widgets, for updating, and a crash flow where a pop-up hands the failed process straight to your default agent to read the logs and debug. When an OS update threatened 48 hours of customization, Codex built a private Git repo of the config and an update hook that backs up, updates, reviews what landed, and reloads.

The bigger point is DHH's "malleable OS": the agent is not an app running on the operating system, it can reach the source, so your Omarchy and someone else's end up genuinely different machines. It also runs on hardware the big vendors have stopped supporting, including M1 and M2 Macs, at a moment when a Mac mini has a 12-week wait. It is not set-and-forget computing - this is for people who want the customization and will own it. Sash is buying a KVM switch to make it his daily driver.

Key takeaways:

• Check the closet before you buy an agent machine. Omarchy installed in under five minutes on an old i7 ThinkCentre with 16 GB of RAM, and it runs on M1 and M2 Macs that can no longer take the latest macOS.
• Use the agent as a tutor before you use it as a builder. Ask it to walk you through the hotkeys and let it move the windows while you watch - that is how Sash learned tiling in 20 minutes.
• Ask the agent what skills and context it has on the system before you ask it to change anything. On Omarchy that question surfaced the built-in manuals for plugins, widgets, updates and crash diagnosis.
• Have the agent build its own safety net before you customize heavily: a private Git repo of your config and an update hook that backs it up, updates, and reloads what the update touched.
• Find a USB stick with at least six gigs before you start, or an SD card adapter. Sash lost 90 minutes to that alone.
