Information: You may need to update /etc/fstab.

If you are on ubuntu or anoter debian based system you can install debootstrap using apt. Otherwise follow the bouncing prompt from the link above.

apt install debootstrap

set up target root filesystem

mke2fs -j /dev/sdb3

bootstrap the root file system

mkdir /mnt/debinst
mount /dev/sdb3 /mnt/debinst
debootstrap --arch amd64 bookworm /mnt/debinst http://ftp.us.debian.org/debian

set up mounts for chroot.

mount -t proc proc /mnt/debinst/proc
mount -t sysfs /sys /mnt/debinst/sys
mount --bind /dev /mnt/debinst/dev
mount --bind /dev/pts /mnt/debinst/dev/pts
LANG=C.UTF-8 chroot /mnt/debinst /bin/bash

Back on the chroot

.... second stage may not be needed ....
/debootstrap/debootstrap --second-stage
.... if you did the above this shouldnt be needed either ....
apt install makedev
cd /dev

adduser joe
adduser feurig

apt install sudo
visudo
passwd -u root
passwd root
nano ~root/.ssh/authorized_keys

copy the entire /etc/ssh/ directory so the host keys dont change
