This guide draws heavily on Raspberry_Pi_2

What you need

Raspberry PI 4
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.
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: +128M ↵
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

Get the Funtoo Files Onto the SD Card

Download the Necessary Files

The next step is to get the kernel, and boot firmware for the Raspberry Pi 4 from funtoo.

root # cd /mnt/funtoo
root # wget https://code.funtoo.org/bitbucket/users/pnoecker/repos/666/raw/pi-boot.tar.gz
root # tar -xf pi-boot.tar.gz

Grab the latest stage 3 file: Subarches

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 -xpf stage3*

Pre-boot Configuration

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

/mnt/funtoo/etc/portage/make.conf

FEATURES="-pid-sandbox"

Edit your fstab file so everything mounts correctly on boot:

root # nano /mnt/funtoo/etc/fstab

/mnt/funtoo/etc/fstab

proc /proc proc defaults 0 0
LABEL=BOOT /boot vfat noauto,noatime 1 2
LABEL=FUNTOO / ext4 noatime 0 1

root # nano /mnt/funtoo/boot/config.txt

/mnt/funtoo/boot/config.txt

kernel=kernel8.img
disable_overscan=0

Chrooting into your new installation

for a good time install Package:Fchroot

First, copy the newly installed file qemu-arm to the Raspberry Pi's filesystem:

root # cp -v /usr/bin/qemu-arm /mnt/funtoo/usr/bin/
root # cp -v /usr/bin/qemu-aarch64 /mnt/funtoo/usr/bin/

Next, 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 && emerge -avuND @world

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

Log in using the password you created earlier. The first thing you'll want to do is fix the clock, set your time zone and sync your portage tree.

Because the Raspberry Pi does not have a hardware clock, you'll need to set the date and time right away. Later on we'll make sure we can get the correct time at boot via NTP, but for now we need to do it manually

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

Next, set your timezone:

root # ln -sf /usr/share/zoneinfo/YOURTIMEZONE /etc/localtime

Now we need make sure we can connect to the internet:

root # rc-update add dhcpcd default

kitchen SINK:

root # ego sync

Set your profile with epro:

root # epro list 
root # epro flavor server

root # rc-update add busybox-ntpd sysinit
root # rc-update add swclock boot
root # rc-update del hwclock 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.
