mkinitcpio Log Generator - Arch Linux Initramfs Simulator | Fakeact

Generate mkinitcpio initramfs creation logs with hooks, modules, and firmware warnings. Perfect for Arch Linux documentation and boot troubleshooting tutorials.

Terminal preview

Press Ctrl + C to exit. Output is simulated for demo purposes only.

Overview

This module simulates initramfs build, hook sequence, and firmware warnings log events with realistic pacing.

It is designed for demos, log pipeline testing, and documentation where the real stack is unavailable.

All output is generated locally in the browser and is safe to run.

Use cases

  • Demo mkinitcpio workflows without running the real stack.
  • Test log ingestion rules around initramfs build and firmware warnings events.
  • Create screenshots, recordings, or training material on demand.

Notes

  • All output is simulated text; no system changes are made.
  • Refresh the page to restart the log stream.
  • Use the CLI for longer sessions or offline demos.

Sample output

==> Building image from preset: /etc/mkinitcpio.d/linux.preset: 'default'
  -> Running build hook: [base]
  -> Running build hook: [block]
==> WARNING: Possibly missing firmware for module: ahci
==> Creating gzip-compressed initcpio image: /boot/initramfs-linux.img
==> Image generation successful

FAQ

Is mkinitcpio output real?

No. It is a simulator that prints log text only.

Can I control the speed of mkinitcpio?

Yes. The CLI supports speed and repeat options, and the web page can be refreshed.

Does mkinitcpio change my system?

No. It does not install, update, or modify anything.

What's more about mkinitcpio?

mkinitcpio builds initramfs images on Arch Linux. Its output shows build hooks, firmware warnings, and image creation.

This module mimics that output for documentation and testing without running mkinitcpio on a real system.

Stack Overflow Questions

Popular questions and answers from Stack Overflow related to mkinitcpio.

How to fix "Possibly missing firmware" warning in mkinitcpio?
Accepted Answer

Install the missing firmware package (often linux-firmware). For specific hardware, find the firmware package in AUR. The warning usually does not prevent booting unless you need that specific hardware.

What are mkinitcpio hooks and how do they work?
Accepted Answer

Hooks add functionality to initramfs. Common hooks: base (essential), udev (device management), filesystems (fs support), keyboard (input). Order matters - udev should come before autodetect.

How to regenerate initramfs with mkinitcpio?
Accepted Answer

Run: sudo mkinitcpio -P to regenerate all presets. For specific kernel: mkinitcpio -p linux. For specific config: mkinitcpio -c /etc/mkinitcpio.conf -g /boot/initramfs-linux.img.

What is the difference between MODULES and HOOKS in mkinitcpio?
Accepted Answer

MODULES: specific kernel modules to always include (e.g., nvidia, ext4). HOOKS: scripts that add functionality and may include multiple modules. MODULES is manual, HOOKS is more automated.

How to add custom modules to initramfs?
Accepted Answer

Edit /etc/mkinitcpio.conf, add to MODULES array: MODULES=(module1 module2). Then run mkinitcpio -P. For hooks adding modules automatically, check hook documentation.

How to fix boot issues caused by mkinitcpio?
Accepted Answer

Boot from live USB, mount root partition, chroot in, check /etc/mkinitcpio.conf for errors, regenerate with mkinitcpio -P. Common issues: missing hooks, wrong filesystem module.

What compression algorithms does mkinitcpio support?
Accepted Answer

Supported: gzip (default), bzip2, lzma, xz, lzop, lz4, zstd. Set in mkinitcpio.conf: COMPRESSION="zstd". zstd offers good compression with fast decompression. lz4 is fastest.

How to include files in initramfs?
Accepted Answer

Use FILES array: FILES=(/etc/modprobe.d/myconfig.conf). For directories/patterns, create a custom hook in /etc/initcpio/install/ that copies files.

How to debug mkinitcpio boot problems?
Accepted Answer

Add break=premount or break=postmount to kernel cmdline for emergency shell. Use rd.debug for verbose output. Check journalctl -b for boot logs after successful boot.

What is the autodetect hook in mkinitcpio?
Accepted Answer

autodetect scans your system and includes only needed modules, making initramfs smaller. Place after udev. Remove autodetect for generic/portable images that need all modules.
