PureOS provides convenient pre-built images for use on computer and in Virtual Machines, you can find those images here: https://downloads.puri.sm/ It is also possible to build a PureOS image. Purism does this when we want to test the reproducibility of a PureOS image. Here's how it's done; 1. **Prepare an appropriate environment. ** //If you're already running PureOS on your build machine, then you're all set. If you're running another GNU/Linux distribution it is likely best to set up a chroot or to use a tool like debspawn (discussed below.)// 2. **Install live-build and other tools** ``` $ apt install live-build git ca-certificates ``` 3. **Clone via git our configuration for PureOS** ``` $ cd /srv && git clone https://source.puri.sm/pureos/infra/make-live.git $ cd /srv/make-live ``` Currently we build a number of images; gnome-live, gnome-oem, plasma-live. Exporting the type of image you want into your environment is needed if you want to overide the default; ``` $ export FLAVOR="gnome-oem" ``` If no FLAVOR variable is set, the GNOME Live Flavor will be built by default. 4. Run `lb config` 5. Run `lb build` 6. **Have fun with a fresh new PureOS image!**
