The Linux guest that runs in this page contains software under the GNU General Public License version 2 (the Linux kernel, BusyBox, and OpenJDK under GPL-2.0 with the Classpath Exception) and version 3 with the GCC Runtime Library Exception (libgcc, libstdc++). For this guest image version, the complete corresponding source code is available at no charge from our public repository github.com/xuwaters/xvm-sources at commit
29f297441da1023d6f96e192d42aa1cf4f07b5b4: the upstream source of the Linux kernel, BusyBox and OpenJDK at the exact tag this image was built from, and Alpine's build files with every patch. Every patch we applied, the kernel configuration, and the scripts used to build and assemble the binaries, with the digests of the public container images they run in (tools.txt), are in this directory. The source remains available for as long as we serve this version and for at least three years afterwards. This page lists each source archive the build used with its SHA-256 and the tag and commit in that repository it corresponds to;index.jsonhas the same in machine-readable form.
