User:Pnoecker/Raspberry Pi 4

This guide draws heavily on Raspberry_Pi_2

What you need

1. Raspberry PI 4
2. An existing Linux install Undead_USB_Install built with fchroot is a solid choice if you do not have funtoo installed on a hard drive.
3. A suitable SD card for your PI.

Prepare your SD card

List the device to be partitioned, mine is on /dev/sdc

root # lsblk -o name,size,label,partlabel

root # gdisk /dev/sdc

Command: o ↵
This option deletes all partitions and creates a new protective MBR.
Proceed? (Y/N): y ↵

Command: n ↵
Partition Number: 1 ↵
First sector: ↵
Last sector: +1M ↵
Hex Code: EF02 ↵
Command: c ↵
Partition number: 1
Enter name: BIOS Boot

Command: n ↵
Partition Number: 2 ↵
First sector: ↵
Last sector: +384M ↵
Hex Code: EF00 ↵
Command: c ↵
Partition number: 2
Enter name: BOOT

Command: n ↵
Partition Number: 3 ↵
First sector: ↵
Last sector: ↵
Hex Code:  8305 ↵
Command: c ↵
Partition number: 3
Enter name: FUNTOO

Command: w ↵
Do you want to proceed? (Y/N): Y ↵

Create File Systems

Next, we need to create file systems on the partitions:

root # mkfs.vfat -F 32 /dev/sdc2
root # fatlabel /dev/sdc2 "BOOT"
root # mkfs.ext4 /dev/sdc3
root # e2label /dev/sdc3 "FUNTOO"

Prepare Your Boot Partition

Make mount points for your boot and root partitions on the SD card:

root # mkdir /mnt/funtoo

Mount your SD card:

root # mount /dev/sdc3 /mnt/funtoo 
root # mkdir /mnt/funtoo/boot
root # mount /dev/sdc2 /mnt/funtoo/boot

Download the Necessary Files

Grab the latest Arm64_generic stage 3 file: Subarches

root # cd /mnt/funtoo
root # wget https://build.funtoo.org/1.4-release-std/arm-64bit/arm64_generic/2020-09-07/stage3-arm64_generic-1.4-release-std-2020-09-07.tar.xz

Extract the stage 3:

root # tar --numeric-owner --xattrs --xattrs-include='*' -xpf stage3*

Pre-boot Configuration

Edit your make.conf file to enable fchroot to compile:

   /mnt/funtoo/etc/portage/make.conf

FEATURES="-pid-sandbox"
PORTAGE_TMPDIR="/run"
GRUB_PLATFORMS="uboot"

Edit your fstab file so everything mounts correctly on boot:

root # lsblk -o name,size,partuuid
root # nano /mnt/funtoo/etc/fstab

   /mnt/funtoo/etc/fstab

proc /proc proc defaults 0 0
PARTUUID=1727e25d-a9c4-455c-95e7-8feb7f28622d /boot vfat noauto,noatime 1 2
PARTUUID=f91ca0ab-74cf-4381-ae50-11ffb853fb3b / ext4 noatime 0 1

Chrooting into your new installation

for a good time install Package:Fchroot

as root, start the binfmt service:

root # /etc/init.d/binfmt restart

Finally perform the usually chroot routine (as described in detail in the Funtoo Linux Installation Guide):

root # cd /mnt/funtoo
root # mount --rbind /run run
root # fchroot .

• Set yo password

root # passwd && ego sync

root # echo "media-libs/raspberrypi-userland-bin **" >> /etc/portage/package.accept_keywords
root # echo "sys-boot/raspberrypi-firmware **" >> /etc/portage/package.accept_keywords
root # echo "sys-kernel/raspberrypi-image **" >> /etc/portage/package.accept_keywords
root # emerge raspberrypi-userland-bin raspberrypi-firmware raspberrypi-image

root # nano /boot/config.txt

   /boot/config.txt

dtparam=audio=on
dtoverlay=vc4-fkms-v3d
max_framebuffers=2
arm_64bit=1

root # lsblk -o name,size,partuuid
root # nano /boot/cmdline.txt

   /boot/cmdline.txt - Stifler's Mom

console=serial0,115200 console=tty1 root=PARTUUID=f91ca0ab-74cf-4381-ae50-11ffb853fb3b rootfstype=ext4 elevator=noop fsck.repair=yes rootwait

Clean unmount

Make sure all buffers have been flushed and unmount the temp directories:

root # exit
root # cd .. && sync 
root # umount -lR funtoo

Booting the Raspberry Pi 4

root # /etc/init.d/busybox-ntpd restart
or
root # date MMDDHHMMCCYY

Next, set your timezone:

root # ln -sf /usr/share/zoneinfo/America/Detroit /etc/localtime

Set your profile with epro:

root # epro list 
root # epro flavor server

root # rc-update add dhcpcd default
root # rc-update add busybox-ntpd sysinit
root # rc-update add swclock boot
root # rc-update del hwclock boot
root # rc-update del swap boot

Now you can follow the Funtoo Install documentation to continue configuring your system. You'll definitely want to look into No results if you are going to be adding lots of software to your system.
