- OpenSourceWatershed is a project aimed at understanding the relationship between distributions (downstream) and the individual software components (upstream). It is the basis for a larger study of distributions and their evolution. It is distrology. The aggregate analysis is done over a variety of packages. The three forms of analysis are percent obsolete, the average number of newer releases per package and the time since the oldest new release. In other words the lag is the amount of time a distro had to move to a newer package.

- archinstaller - Automated installation script for arch linux written in bash. It works similar to preseeding the debian installer d-i. OLD, still kinda interesting.
- Arch Anywhere ISO - contains an automated install script giving you the ability to install a fully custom Arch Linux system in minutes. Write the Arch Anywhere ISO to a CD or USB, boot it up from your computer or VirtualBox, and type 'arch-anywhere'.

- https://wiki.archlinux.org/index.php/archiso - a small set of bash scripts capable of building fully functional Arch Linux live CD/DVD/USB images. It is the same tool used to generate the official images, but since it is a very generic tool, it can be used to generate anything from rescue systems, install disks, to special interest live CD/DVD/USB systems, and who knows what else. Simply put, if it involves Arch on a shiny coaster, it can do it. The heart and soul of Archiso is mkarchiso. All of its options are documented in its usage output, so its direct usage will not be covered here. Instead, this wiki article will act as a guide for rolling your own live media in no time!
- https://wiki.archlinux.org/index.php/archboot - a set of scripts to generate bootable media for CD/USB/PXE, designed for installation or rescue operation.
The difference between archboot and the archiso install media;
- It provides an additional interactive setup and quickinst script.
- It contains [core] repository on media.
- It runs a modified Arch Linux system in initramfs.
- It is restricted to RAM usage, everything which is not necessary like man or info pages etc. is not provided.
- It doesn't mount anything during boot process.
- It supports remote installation through ssh.

Red Hat Enterprise Linux (RHEL)
"Red Hat Enterprise Linux is available only through a paid subscription service that provides access to software updates and varying levels of technical support."
"Since Red Hat Enterprise Linux is based completely on free and open source software, Red Hat makes available the complete source code to its enterprise distribution through its FTP site to anybody who wants it. Accordingly, several groups have taken this source code and compiled their own versions of Red Hat Enterprise Linux, typically with the only changes being the removal of any references to Red Hat's trademarks and pointing the update systems to non-Red Hat servers. Groups which have undertaken this include CentOS (the 8th most popular Linux distribution as of November 2011), Oracle Linux, Scientific Linux, White Box Enterprise Linux, StartCom Enterprise Linux, Pie Box Enterprise Linux, X/OS, Lineox, and Bull's XBAS for high-performance computing. All provide a free mechanism for applying updates without paying a service fee to the distributor.""
If going down the based-on-RHEL route, consideration needs to be paid towards the update delay of the distros when a new RHEL release comes out.
- Fedora is an RPM-based, general purpose collection of software, including an operating system based on the Linux kernel, developed by the community-supported Fedora Project and owned by Red Hat.
- Fedora Spins are alternative versions of Fedora, tailored for various types of users via hand-picked application sets or customizations.
- Extra Packages for Enterprise Linux (or EPEL) is a Fedora Special Interest Group that creates, maintains, and manages a high quality set of additional packages for Enterprise Linux, including, but not limited to, Red Hat Enterprise Linux (RHEL),CentOS and Scientific Linux (SL). EPEL packages are usually based on their Fedora counterparts and will never conflict with or replace packages in the base Enterprise Linux distributions. EPEL uses much of the same infrastructure as Fedora, including buildsystem, bugzilla instance, updates manager, mirror manager and more.

- NixOS is a GNU/Linux distribution that aims to improve the state of the art in system configuration management. In existing distributions, actions such as upgrades are dangerous: upgrading a package can cause other packages to break, upgrading an entire system is much less reliable than reinstalling from scratch, you can’t safely test what the results of a configuration change will be, you cannot easily undo changes to the system, and so on. We want to change that.
- GNU Linux-libre is a project to maintain and publish 100% Free distributions of Linux, suitable for use in Free System Distributions, removing software that is included without source code, with obfuscated or obscured source code, under non-Free Software licenses, that do not permit you to change the software so that it does what you wish, and that induces or requires you to install additional pieces of non-Free Software.

- https://en.wikipedia.org/wiki/386BSD - sometimes called "Jolix", is a discontinued free Unix-like operating system based on BSD, first released in 1992. It ran on PC-compatible computer systems based on the 32-bit Intel 80386 microprocessor. 386BSD innovations include role-based security, ring buffers, self-ordered configuration and modular kernel design. The BSDs for PC descend from it.
After the release of 386BSD 0.1, a group of users began collecting bug fixes and enhancements, releasing them as an unofficial patchkit. Due to differences of opinion between the Jolitzes and the patchkit maintainers over the future direction and release schedule of 386BSD, the maintainers of the patchkit founded the FreeBSD project in 1993 to continue their work. Around the same time, the NetBSD project was founded by a different group of 386BSD users, with the aim of unifying 386BSD with other strands of BSD development into one multi-platform system. Both projects continue to this day.

- GNU - offers a Unix-compatible system that would be 100% free software. Not 95% free, not 99.5%, but 100%. The name of the system, GNU, is a recursive acronym meaning GNU's Not Unix—a way of paying tribute to the technical ideas of Unix, while at the same time saying that GNU is something different. Technically, GNU is like Unix. But unlike Unix, GNU gives its users freedom. Completely free system distributions (“distros”) meeting this goal are available today, many using the Linux-libre kernel (the relationship between GNU and the Linux kernel is described more fully elsewhere). The GNU packages have been designed to work together so we could have a functioning GNU system. It has turned out that they also serve as a common “upstream” for many distros, so contributions to GNU packages help the free software community as a whole. Naturally, work on GNU is ongoing, with the goal to create a system that gives the greatest freedom to computer users. GNU packages include user-oriented applications, utilities, tools, libraries, even games—all the programs that an operating system can usefully offer to its users.
- GuixSD is an advanced distribution of the GNU operating system developed by the GNU Project —which respects the freedom of computer users.
- Guile is an interpreter and compiler for the Scheme programming language, a clean and elegant dialect of Lisp. Guile is a library designed to help programmers create flexible applications. Guile is an efficient virtual machine that executes a portable instruction set generated by its optimizing compiler, and integrates very easily with C and C++ application code. In addition to Scheme, Guile includes compiler front-ends for ECMAScript and Emacs Lisp (support for Lua is underway), which means your application can be extended in the language (or languages) most appropriate for your user base. And Guile's tools for parsing and compiling are exposed as part of its standard module set, so support for additional languages can be added without writing a single line of C.

Unix done 'better'. Ideas from Plan 9 made it into Linux, like more things being files.
"In Plan 9, each process has its own filesystem tree, and other programs can expose themselves to this process as file servers, meaning that data internal to the programs can be accessed via the same read, write, delete, etc. calls as files. For example, when running under rio, the Plan 9 window system, the current window contents are available at /dev/window and you can write draw calls to /dev/draw to do graphics."

- http://wiki.osdev.org/Mkisofs - mkisofs is effectively a pre-mastering program to generate the iso9660 filesystem - it takes a snapshot of a given directory tree, and generates a binary image which will correspond to an iso9660 filesystem when written to a block device
- https://wiki.debian.org/genisoimage - forked mkisofs alternative
- https://en.wikipedia.org/wiki/El_Torito_(CD-ROM_standard) - an extension to the ISO 9660 CD-ROM specification. It is designed to allow a computer to boot from a CD-ROM. It was announced in November 1994 and first issued in January 1995 as a joint proposal by IBM and BIOS manufacturer Phoenix Technologies.
- https://www.mankier.com/1/isohybrid - modifies an ISO 9660 image generated with mkisofs, genisoimage, or compatible utilities, to be bootable as a CD-ROM or as a hard disk.
Wait, don't do this automatically and at once! Isohybrid should be run only once, and many iso files are already treated before uploading to the internet. The Ubuntu iso files are already treated with isohybrid. Use isohybrid only, if the USB drive does not boot after installing using mkusb. Run fdisk on the file. If it shows anything meaningful, it is hybrid.
- ISOLINUX - a (syslinux) boot loader for Linux/i386 that operates off ISO 9660/El Torito CD-ROMs in "no emulation" mode. This avoids the need to create an "emulation disk image" with limited space (for "floppy emulation") or compatibility problems (for "hard disk emulation").

- UNetbootin allows you to create bootable Live USB drives for Ubuntu, Fedora, and other Linux distributions without burning a CD. It runs on Windows, Linux, and Mac OS X. You can either let UNetbootin download one of the many distributions supported out-of-the-box for you, or supply your own Linux .iso file if you've already downloaded one or your preferred distribution isn't on the list.

- MultiBootUSB - a software / installer which allows user to install multiple Live Linux Distros in to a single USB drive / Pendrive / Flash drive and able to boot from it. USB can be tested without reboot using inbuilt QEMU. Uses syslinux.
- MultiSystem – Create a MultiBoot USB from Linux. Uses GRUB
- https://github.com/aguslr/multibootusb - not the same as above...
- YUMI (Your Universal Multiboot Integrator), is the successor to our MultibootISOs. It can be used to create a Multiboot USB Flash Drive containing multiple operating systems, antivirus utilities, disc cloning, diagnostic tools, and more. Contrary to MultiBootISOs which used grub to boot ISO files directly from USB, YUMI uses syslinux to boot extracted distributions stored on the USB device, and reverts to using grub to Boot Multiple ISO files from USB, if necessary. Windows.
- out of date in AUR. home page doesn't have Linux version currently, too broken apparently.

- not usb-creator in AUR
- http://www.sarducd.it/ - SARDU multiboot USB and DVD creator. Windows (and Linux??). Free for personal use, not in AUR.
- LinuxLive USB Creator is a completely free and open-source software for Windows only. It has been built with simplicity in mind and it can be used by anyone. All you have to do is to pick up a Linux in the list and give it a try.
- RMPrepUSB - allows the Windows user to easily and quickly 'roll their own' multiboot USB drive. It allows the user to quickly test, partition, format, install a boot manager, extract or copy files and then test a multiboot (aka multipass) USB bootable drive. It can also make or restore an image and much more. Multiboot 'point-and-shoot' utilities like YUMI or XBOOT are excellent, however they don't support every different ISO or image. You will learn too enjoy making your own personal multiboot drive using RMPrepUSB!
