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 11.1rc5 (June 2, 2020), based on Core-11.1. 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 seven 1440KB floppies. The floppy version is a modified Core-7.x which downloads and boots NetbootCD 11.1.
To build NetbootCD yourself, grab the contents of the NetbootCD Git repo. You'll also want to put CorePlus-9.0.iso in the same folder as Build.sh; if you don't, Build.sh will download it for you.

Source for software in version 9.0 can be found at http://tinycorelinux.net/9.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).
