User:Pnoecker/Raspberry Pi 4

This guide draws heavily on Raspberry_Pi_2, Undead_USB_Install, and Install

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 # cgdisk /dev/sdc

• delete everything:

Command: new ↵
First sector:  ↵
Size:  +1M ↵
Hex Code: EF02 ↵
Name: BIOS Boot ↵

• scroll down to the large chunk of free space:

Command: new ↵
First sector: ↵
Last sector: +256M ↵
Hex Code: EF00 ↵
Name: BOOT ↵

• scroll down to the large chunk of free space:

Command: new ↵
First sector: ↵
Last sector: ↵
Hex Code:  8305 ↵
Name: FUNTOO ↵

Disk Drive: /dev/sdc
                            Size: 62333952, 29.7 GiB

Part. #     Size        Partition Type            Partition Name
----------------------------------------------------------------
            1007.0 KiB  free space
   1        1024.0 KiB  BIOS boot partition	  BIOS Boot
   2        256.0 MiB   EFI System                BOOT
   3        29.5 GiB    Linux ARM64 root (/)      FUNTOO

Command: write ↵
Do you want to proceed? (Y/N): yes ↵
Command: quit ↵

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:

root # nano /mnt/funtoo/etc/portage/make.conf

   /mnt/funtoo/etc/portage/make.conf

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

• Edit your fstab file so everything mounts correctly on boot:
• Raspberry pi only supports partuuid and partlabel loading:

root # nano /mnt/funtoo/etc/fstab

   /mnt/funtoo/etc/fstab

proc /proc proc defaults 0 0
PARTLABEL=BOOT /boot vfat noauto,noatime 1 2
PARTLABEL=FUNTOO / 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 # nano /boot/cmdline.txt

   /boot/cmdline.txt - Stifler's Mom

console=serial0,115200 console=tty1 root=PARTLABEL=FUNTOO rootfstype=ext4 elevator=noop fsck.repair=yes rootwait

Set your timezone:

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

• Set Services:

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

   Note

you should probably test that your pi boots at this point BEFORE emerging everything.

• Set your profile:

root # epro list 
root # epro flavor desktop
root # epro mix-in xfce
root # echo "media-plugins/alsa-plugins pulseaudio" >> /etc/portage/package.use
root # echo "net-print/cups -zeroconf" >> /etc/portage/package.use
root # echo "gnome-base/gvfs -http" >> /etc/portage/package.use
root # emerge xorg-x11 pulseaudio networkmanager lightdm xfce4-meta

root # emerge -avuND @world

Install/Stage3_Desktop

Clean unmount

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

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

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.
