About

This project is inspired by oddlama but differs in several important ways.

Key differences from the orginal project

• Openrc support only

• Seperated boot drive

• Support only EFI system

• Encryption using GPG-keyfile only

• File system:

  • btrfs for root
  • vfat for boot
  • ext4 for boot extended

• Btrfs subvolumes:

  • root,home,etc,var,log,tmp

• No interactive GUI configuration — everything is defined in gentoo.conf

• Uses gentoo-sources; the user may choose between make defconfig or manual menuconfig.

• Contribution documentation for required kernel modules is provided in contrib/kernel_modules.md.

Usage

First boot into a live cd from Arch linux or Endeavor os (only this Live cd have been tested):

pacman -Sy git # (Archlinux) Install git in live environment
git clone "https://github.com/Minerte/gentoo-install-custom"
cd gentoo-install-custom

Edit the gentoo.conf file

• set X from create_boot_storage_disk_layout type=efi /dev/sdX to a USB drive.
• set X from create_gpg_disk_layout swap=8GiB luks=true root_fs=btrfs /dev/sdX to main disk where root will be.
• (Optional) swap size is set at 8Gib by default but it can be change.
• (Optional) an alternative stage3 tarball (default is hardened-selinux-openrc).

And then begin installtion with:

./install

Kernel config
During installation, the script will prompt you to select a kernel version. Afterward, it will ask whether you want to run make defconfig:

• Yes — starts from the kernel defaults, but you must still enable several required modules (see contrib/kernel_modules.md).
• No — menuconfig opens with no preconfiguration.

Finish
After the installation completes, you may chroot into the new system to perform any additional configuration.
