COPY-MODLOOP(8)

📦 version 3.22.0, in alpine 3.24

💅 copy-modloop(8) — like, the system manager's manual bestie

okay so welcome to copy-modloop, a page from the System Manager's Manual section 8 (that's the admin-tools girlies ✨). pull up a chair, grab a boba, and lemme tell you about this tiny little script that does one job and does it beautifully.

✨ NAME ✨

copy-modloop — literally just copies kernel modules from modloop 🎀

✨ SYNOPSIS ✨

copy-modloop [-h]

that's it. that's the whole vibe check. one optional flag, no drama 💅

✨ DESCRIPTION ✨

okay so here's the tea 🍓: copy-modloop copies kernel modules from the modloop loopback device over to /lib/modules, and then it unmounts the modloop. boom. done. iconic behaviour, no notes.

where you'll actually see this queen in action: on Alpine Live ISO images, to make the kernel modules persistent after a disk installation. like, you install to disk, and you want your modules to still be there after reboot? yeah. that's her moment. main character energy fr fr 👑

⚠️ important caveat bestie, do not skip this: the modloop service must be running when the script starts. no service, no copy, no slay. and heads up — the script stops the modloop service after it's done copying the modules. so it's a one-way trip. she copies, she cleans up, she leaves. periodt.

✨ OPTIONS ✨

  • -h — display usage information and exit. your classic "wait what does this do again" button 🫶

✨ EXIT STATUS ✨

  • 0 — success! she ate, no crumbs, everything worked 💖
  • non-zero — something went wrong 😭 an error occurred, or the modloop service wasn't started in the first place. yeah. that second one. that's the one that gets you.

✨ SEE ALSO ✨

the whole friend group honestly 🌸 go read them, they're all valid.

✨ AUTHORS ✨

Natanael Copa <ncopa@alpinelinux.org> and others 🧚 (yes, "and others" — the group chat of contributors, iykyk)

okay that's the whole page, go be persistent with your modules bestie 💜
