NetbootCD is a Linux live CD based on Tiny Core Linux. The live CD allows the user to download and run one of several Linux netboot installers, which can install a full GNU/Linux system with only a hard drive and Internet connection.
Some of the distributions supported by NetbootCD are prerelease distributions (such as Debian testing) or development/rolling-release distributions (openSUSE Tumbleweed, Fedora Rawhide, Debian sid.) Because NetbootCD downloads the latest installer, which in turn downloads the latest system components, you can install a fully up-to-date system without burning a new CD.
The following distributions are installable from the current NetbootCD:
The current version of NetbootCD is version 7.2.1 (October 26, 2016), based on Core-7.2. The ISO image can be burned to a CD/DVD or written to a flash drive.
There are two versions of NetbootCD: the standalone version (NetbootCD.iso) and a version where NetbootCD is combined with CorePlus (NetbootCD+CorePlus.iso.) The latter includes everything in CorePlus; it boots to the X11 desktop and then lets you run NetbootCD (by typing "netboot") after exiting to the prompt.
NetbootCD is also available on a set of 1440KB floppies. (See here for how it works.) The floppy version does not include pxe-kexec. In most cases, only the first floppy is necessary - it can load the newest version of NetbootCD from the web using iPXE if you have an active network connection at boot.
To build NetbootCD yourself, grab the contents of the NetbootCD Git repo at tag v7.2.1. You'll also want to put CorePlus-7.2.iso in the same folder as Build.sh; if you don't, Build.sh will download it for you.

Source for software in version 7.2.1 can be found at http://tinycorelinux.net/7.x/x86/release/src/ and https://github.com/IsaacSchemm/netbootcd-source. The source code to components not in Tiny Core is in the netbootcd-source repo, but the build script and related components are in the netbootcd repo (see the download link above).
