Puppy Linux is yet another Linux distribution. What's different here is that Puppy is extraordinarily small, yet quite full-featured. Puppy boots into a ramdisk and, unlike live CD distributions that have to keep pulling stuff off the CD, it loads into RAM. This means that all applications start in the blink of an eye and respond to user input instantly. Puppy Linux has the ability to boot off a flash card or any USB memory device, CDROM, Zip disk or LS/120/240 Superdisk, floppy disks, internal hard drive. It can even use a multisession formatted CD-RW/DVD-RW to save everything back to the CD/DVD with no hard drive required at all.

GNOME OS is an experimental, immutable Linux distribution that ships the latest in-development GNOME desktop, core applications and stack. It serves as a reference for developers and testers. It is designed around the modern systemd and GNU-based userland built from the Freedesktop SDK. Initially, GNOME OS used a library and set of utilities called OSTree to deploy the root filesystem and manage updates, but later migrated to "systemd-sysupdate" which offers enhanced immutability, auto-updating, adaptability, factory reset, uniformity and other modernised security properties. GNOME OS can be loaded as a live image in Boxes, VirtualBox, QEMU and other virtualisation software, but it can also be installed on a standard x86_64 hardware. The distribution does not support traditional package management; however, additional software applications can be installed via the Flatpak utility which is supported out of the box.

The project started with Address Space Layout Randomization (ASLR) as an initial focal point and is now implementing further exploit mitigation techniques.

Devuan GNU+Linux is a Linux distribution forked from Debian in 2015. The project's primary goal is to provide a variant of Debian without the complexities and dependencies of systemd, an init system and services manager originally developed by Red Hat and later adopted by most other Linux distributions. Devuan's initial beta release was made available in April 2016, together with an upgrade path from Debian 7.0 "Wheezy" and a possibility to switch to Devuan from Debian 8.0 "Jessie". The distribution adopted Xfce as its default desktop.
