What you need

Raspberry PI 4
An existing Funtoo Linux install or Livecd (Livecd is a solid choice if you do not have funtoo installed on a hard drive)
a 32GB or larger SD card

Prepare your SD card

Target your drive as outlined in the official install. Install/Prepare_Disk

Use parted to create partitions:

root # emerge parted dmidecode

root # wipefs -a /dev/funtoo
root # parted /dev/funtoo --script mklabel msdos
root # parted /dev/funtoo unit MB mkpart primary fat32 1 128
root # parted /dev/funtoo set 1 boot on
root # parted -s /dev/funtoo unit mib mkpart primary linux-swap 122 2168
root # parted /dev/funtoo unit MB mkpart primary ext4 2273 100%
root # partprobe

Or use fdisk instead:

delete everything:

root # wipefs -a/dev/funtoo

Make a new MS-DOS disklabel. Add a new partition - this will be 128Mb for /boot

root # fdisk /dev/funtoo

Command (m for help): n
Partition type
   p   primary (0 primary, 0 extended, 4 free)
   e   extended (container for logical partitions)
Select (default p): p
Partition number (1-4, default 1): 1
First sector (2048-15523839, default 2048): 
Last sector, +sectors or +size{K,M,G,T,P} (2048-15523839, default 15523839): +128M

Has created a new partition 1 of type 'Linux' and of size 128 MiB. Add a 2G partition 2 for swap. Put the remaining space in partition 3 for root.

Check with

Command (m for help): p

Using an 8G microSD card it should show

Device     Boot   Start      End  Sectors  Size Id Type
/dev/funtoo1          2048   264191   262144  128M 83 Linux
/dev/funtoo2        264192  4458495  4194304    2G 83 Linux
/dev/funtoo3       4458496 15523839 11065344  5.3G 83 Linux

Set flags and partition types Toggle the bootable flag on partition 1

ommand (m for help): a
Partition number (1-3, default 3): 1

The bootable flag on partition 1 is enabled now. Mark partition 1 as FAT

Command (m for help): t
Partition number (1-3, default 3): 1
Partition type (type L to list all types): c

Changed type of partition 'Linux' to 'W95 FAT32 (LBA)'.

Note

The Pi checks the type of partition 1 in the partition table and will not boot if its 82

Mark partition 2 as swap

Command (m for help): t
Partition number (1-3, default 3): 2
Partition type (type L to list all types): 82

Changed type of partition 'Linux swap / Solaris' to 'Linux swap / Solaris'.

Check again.

Device     Boot   Start      End  Sectors  Size Id Type
/dev/sdk1  *       2048   264191   262144  128M  c W95 FAT32 (LBA)
/dev/sdk2        264192  4458495  4194304    2G 82 Linux swap / Solaris
/dev/sdk3       4458496 15523839 11065344  5.3G 83 Linux

Save the new partition table. Exit fdisk with either w or q

w   write table to disk and exit
  q   quit without saving changes

Create File Systems

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

root # mkfs.vfat -F 32 /dev/funtoo1
root # fatlabel /dev/funtoo1 "BOOT"
root # mkswap -L SWAP /dev/funtoo2
root # mkfs.ext4 /dev/funtoo3
root # e2label /dev/funtoo3 "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/funtoo3 /mnt/funtoo 
root # mkdir /mnt/funtoo/boot
root # mount /dev/funtoo1 /mnt/funtoo/boot

Get the Funtoo Files Onto the SD Card

Download the Necessary Files

Grab the latest Arm64_generic stage 3 file: Subarches

root # cd /mnt/funtoo
root # wget https://area31.host.funtoo.org/stage3-raspi4-1.4-release-std-2022-05-19.tar.xz

Extract the stage 3:

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

Pre-boot Configuration

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

LABEL=BOOT    /boot           vfat    defaults          0       2
LABEL=SWAP   none            swap    sw                0       0
LABEL=FUNTOO    /               ext4    defaults,noatime  0       1
tmpfs /var/tmp/portage tmpfs uid=portage,gid=portage,mode=775,noatime 0 0

Chrooting into your new installation

for a good time install Package:Fchroot

Fchroot in:

root # cd /mnt/funtoo
root #  fchroot --cpu cortex-a72 . su --login
root # export PS1="FUNTOO $PS1"

set your pass

Create new user and set password:

root # echo -e "root\nroot" | passwd root
root # useradd funtoo && echo -e "funtoo\nfuntoo" | passwd  funtoo
root # usermod -a -G wheel,audio,video funtoo
root # echo "funtoo ALL=(ALL) NOPASSWD: ALL" >> /etc/sudoers

Sync tree

root # ego sync

compile in ram

root # mkdir /var/tmp/portage
root # chown portage:portage /var/tmp/portage
root # mount /var/tmp/portage

Emerge necessary ebuilds

root # export FEATURES="-pid-sandbox" ; emerge raspberrypi-userland raspberrypi-firmware raspberrypi-image sys-firmware/raspberrypi-wifi-ucode

Configure driver VC4 and screen resolution:

<div class="note">
<div class="note-head"><i class="fas fa-comment-alt"></i></i>   Note</div><div class="note-body">
{{{1}}}
</div></div>

root # nano /boot/config.txt

/boot/config.txt

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

or:

/boot/config.txt

gpu_mem=128
dtoverlay=vc4-kms-v3d-pi4
max_framebuffers=2
# CEA
#hdmi_group=1
#hdmi_mode=4
# DMT
hdmi_group=2
hdmi_mode=85

Configure kernel line:

root # nano /boot/cmdline.txt

/boot/cmdline.txt

dwc_otg.lpm_enable=0 root=/dev/mmcblk0p3 rootfstype=ext4 fsck.repair=yes usbhid.mousepoll=0 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

Regenerate locales:

root # locale-gen

Exit from fchroot and boot your raspberry pi

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

root # exit
root # sync
root # cd /mnt ; umount -lR funtoo
