PureOS versions

Version Can be debootstrapped Kernel version Comments
Green Not anymore as October 2019: 
E: Couldn't find these debs: ca-certificates pureos-minimal
?
  • Was on the live USB installer before but not anymore
Amber Yes 4.19
  • On the LiveUSB installer as October 2019
  • Based on Debian stable
  • Should be FSDG compliant
Byzantium Yes 5.2
  • "Development target"[1]
  • Based on Debian unstable
  • Not sure if it's FSDG compliant
Landing ? ?
  • Syncronized with Debian testing
  • Probably not fit for use but only as staging for development[2]

Installing

  • PureOS can be installed through the live USB installer
  • Parabola can debootstrap PureOS Amber for all the supported architectures

PureOS on ARM SBCs

u-boot

U-boot has a standard for booting distributions. The easiest way to configure your distribution to boot with u-boot is to create an extlinux.conf configuration file as explaned below. U-boot will then look for it in /boot/extlinux/extlinux.conf (and probably /extlinux/extlinux.conf too) on each partition that it can access.

How to install PureOS on an arm64 SBC 

# qemu-img create -f raw storage.img 2G
# fdisk storage.img # create 1 partition
# udisksctl loop-setup -f storage.img
# mkdir rootfs
# mkfs.ext4 -O ^metadata_csum -O ^64bit /dev/loop0p1
# mount /dev/loop0p1 rootfs
# mkdir -p rootfs/usr/bin
# debootstrap --foreign --arch arm64 amber rootfs https://repo.puri.sm/pureos 
# cp /usr/bin/qemu-aarch64-static rootfs/usr/bin
# LANG=C.UTF-8 chroot rootfs qemu-aarch64-static /bin/bash
# export TERM=xterm-color
# /debootstrap/debootstrap --second-stage

You then need to create the extlinux.conf file in /boot/extlinux/extlinux.conf with the following content: 

menu title Welcome to U-Boot with Extlinux support!

timeout 10

label PureOS GNU/Linux-libre, linux-libre kernel
        kernel /vmlinuz
        append loglevel=8 root=/dev/mmcblk0p1 rw
        fdtdir /usr/lib/linux-image-5.2.0-3-arm64/
        initrd /initrd.img

TODO

  • Add a symlink for /usr/lib/linux-image-5.2.0-3-arm64/ to /ftddir or something like that in Debian and backport it to FSDG distributions that support architecture with devicetree like PureOS
