Using debootstrap
Part 1 : on any computer
Use the following debootstrap command :
debootstrap --foreign --arch=arm64 --include=vim,bsdutils,openssh-client,openssh-server --exclude=ed,nano,tasksel,tasksel-data,vim-tiny --verbose ceres rootfs/ http://fr.deb.devuan.org/merged
You can add some of these (and many more) depending on your needs :
locales,file,net-tools,ca-certificates,bzip2,devuan-keyring,debian-archive-keyring,debian-keyring,diffutils,findutils,iptables,isc-dhcp-client,netbase,ntp,openssh-sftp-server,screen,wireless-tools,minicom
Do not add udev !
It may be possible to add eudev, but somtimes the second stage fails when it is included, so it may be better to add it after the second stage successfully completed (with apt-get install).
Part 2 : on the target
Solution 1 : "init=" kernel parameter
Add "init=/bin/bash" to your kernel command line (in the bootloader configuration), to get something like this (modify and/or add any required option according to your system) :
console=ttyS0,115200n8 root=/dev/mmcblk0p2 rw init=/bin/bash
And once you get the prompt, execute the end of the installation :
export PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin /debootstrap/debootstrap --second-stage
You should then reboot the board.
Solution 2 : mount on existing system
If you've got a running system (any kind of Linux distribution or custom image) for your board and have a solution to mount some external device or remote filesystem on it, then you can use it to run the second stage :
mount /path/to/remote/or/external /mnt/tmp mount -o bind /proc /mnt/tmp/proc mount -o bind /sys /mnt/tmp/sys mount -o bind /dev /mnt/tmp/dev mount -o bind /dev/pts /mnt/tmp/dev/pts chroot /mnt/tmp /bin/bash export PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin /debootstrap/debootstrap --second-stage
And reboot the board once the process has completed.
