Vesta's Approach

• Immutable, immortal, versioned storage of all sources and tools

  • Anything that contributes to the result of a build is considered a source (including compilers, system headers, libraries, etc.)
  • Builds are always done from immutable versions of sources (which guarantees build repeatability)
  • Sources are theoretically immortal (versions can be deleted to reclaim storage space, but once a version is created it can't be re-created with different contents)
