💖 coreos-installer(8) 💖

okay so bestie, welcome to the System Manager's Manual era ✨ this one's all about coreos-installer, and specifically about one lil subcommand that's lowkey a lifesaver when you're digging around inside an initrd.

---

🌸 NAME 🌸

coreos-installer-pxe-ignition-unwrap — show the wrapped Ignition config in an initrd image 🎀

no cap, that's literally the whole job. you point it at an initrd, it pops the lid off and shows you the Ignition config that's hiding inside. it's giving "unwrapping a present but the present is YAML" 🎁

---

✨ SYNOPSIS ✨

coreos-installer-pxe-ignition-unwrap [-h|--help] [-V|--version] [initrd]

---

🦋 DESCRIPTION 🦋

Show the wrapped Ignition config in an initrd image 💅

that's it, that's the vibe. you hand it an initrd image, it finds the wrapped Ignition config and shows it to you. iconic behavior honestly. perfect for when you're staring at a PXE boot setup like "bestie what config is even in here" 😭 and now you can just know.

---

👑 OPTIONS 👑

• -h, --help — print help 🫶 the classic "wait what do the flags do again" button. no shame in it, we all press it.
• -V, --version — print version ⭐ tells you which version of this thing you're running, so you can flex (or troubleshoot).
• [initrd] — initrd image 💖 this is the file you want unwrapped. it's optional, and the default is stdin, so if you don't name a file it'll happily read the initrd image from standard input. pipes? we love pipes.

fr fr, remember: [initrd] defaults to stdin, so no argument = it's reading from the pipe. don't just run it and stare at a frozen terminal wondering why nothing's happening 🙈

---

🌈 VERSION 🌈

and that's the whole page, bestie 🧚 you now know everything this manpage knows. no gatekeeping, no filler, just the facts with a lil sparkle on top 💜

signing off with the official receipts: this page is part of coreos-installer 0.27.0 🎀 stay hydrated, back up your configs, and may your initrds always unwrap on the first try ✨💅🦋
