bcachefs-script

Installs Ubuntu to a new disk using bcachefs as the root partition

It assumes the following:

  1. You're in Ubuntu and connected to internet
  2. You have space for the kernel downloads and time for the compile
  3. You want to use an entire disk and boot using UEFI
  4. You want to use the defaults for format options
wget https://raw.githubusercontent.com/Lyamc/bcachefs-script/main/bcachefs-script.sh; chmod +x bcachefs-script.sh; ./bcachefs-script.sh

How to Use:

  1. Run it, choose "1", pray that the script works on whatever version of OS you have.
  2. Reboot
  3. Run it again, choose "2", pray some more
  4. Reboot into the newly installed OS.

Feel free to give me feedback, I don't know what I'm doing, I just keep doing things till they work. In the future I'll probably add a prompt for adding the formatting options.

bcachefs-update

Installs dependencies, builds and installs bcachefs-tools + kernel from latest git.

Note: This script assumes that you're running Ubuntu

wget https://raw.githubusercontent.com/Lyamc/bcachefs-script/main/bcachefs-update.sh; chmod +x bcachefs-update.sh; ./bcachefs-update.sh

Install on Alpine

Assuming you've already set up networking, the user, and sudo...

# Linux Kernel build dependencies
sudo apk add alpine-sdk linux-headers bash flex bison bc kmod cpio elfutils-dev ncurses-dev openssl-dev perl

# Bcachefs Tools build dependencies
sudo apk add build-base cargo clang17-dev coreutils libaio-dev libsodium-dev llvm17-dev eudev-dev util-linux-dev keyutils-dev lz4-dev userspace-rcu-dev zstd-dev pkgconf zlib

# Build and Install Kernel
