Linux From Scratch (LFS) is a project that provides step-by-step instructions for building a custom Linux system entirely from source code. While traditionally executed on local hardware or virtual machines, the process generates significant intermediate artifacts (tarballs, source code, logs, and temporary tools). This paper explores the viability of using —specifically from providers like Backblaze B2, IDrive e2, or Wasabi’s trial—as a supplementary resource for LFS. We analyze the constraints, security considerations, and practical workflows for integrating cloud storage into the LFS build process without incurring costs. This paper explores the viability of using —specifically
