Saphira Linux

Saphira Linux has a home of its own

Saphira Linux is AKADATA’s source-built, musl/OpenRC server distribution for self-hosted infrastructure. Development, downloads, documentation, packages and the Dragon feature sets now live on the dedicated Saphira Linux website.

Protected release delivery

Signed artifacts, never webroot files

Published images are held outside the document root. A short-lived guest AIE authorizes an explicit POST; PHP records the download start, then Nginx delivers the catalogued file from an internal-only location.

  • No cookies or PHP sessions.
  • No token-bearing URLs or query strings.
  • No filename supplied by the browser is used as a filesystem path.
