How is SkyVision related to Linux From Scratch?

LFS is our school, not our upstream. The Book follows LFS's structure and discipline (we say so on every page, and the Book's license credits it), but SkyVision diverges where a distribution needs to: a package manager (svpkg), signed binary packages, an installer, a maintained kernel config, and a security-update channel. Appendix C of the Book is a literal, honest diff against LFS 12.x.

Why no systemd?

Not as a culture-war statement — as a teaching decision. SkyVision exists so the whole boot path fits in your head: PID 1 is sysvinit, services are short shell scripts in /etc/rc.d, and chapter 9 of the Book explains every line. systemd is fine engineering, but it makes the boot a library call instead of a text file, and text files are the point here.

Why x86-64 only? And what does x86-64-v2 mean?

One architecture means every package is built, tested and documented on what you actually run — small teams that port early ship late. v2 is a CPU feature baseline (SSE4.2, POPCNT — roughly any CPU from 2009 on); compiling against it makes the whole repo measurably faster without abandoning older machines that still matter. ARM64 is a 2.0-era feasibility question, decided with the community.

Is it a rolling release? How do updates work?

Point releases, not rolling. 1.0 is frozen; svpkg up delivers security and bug fixes (1.0.1, 1.0.2 …) that never change behavior, and feature releases (1.1) arrive about twice a year with upgrade notes in the release notes. You can always opt single packages onto newer versions yourself with --from-source — that's what the hybrid design is for.

Can I use it as my daily driver?

If your daily life fits in ~1,800 packages plus what you're willing to build — yes, that's exactly what it's for. The Xfce desktop ISO is a complete workstation. If you need bleeding-edge GPU stacks, Flatpak-everything, or vendor software that only ships .deb/.rpm, a bigger distro will fight you less; the wiki's “coming from Arch/Debian” page is candid about the gaps.

How long does a full from-source build take?

About 55 SBU for the Book's chapters 5–10 — roughly 5 hours on a modern 8-core desktop, a long weekend on a 2-core laptop. You measure your own SBU in section 5.2 and every later estimate scales from it.

Do I have to read the Book to use SkyVision?

No. The Install Handbook gets you a running system in ten minutes, and svpkg works like any package manager. The Book is there for the day you ask “but what is all this, actually?” — which on this distro tends to come early.

Why “SkyVision”, and why is 1.0 called “Firstborn”?

Look at the logo: that smile on Tux belongs to the founder's eldest son. The release names will keep following the family. We are building this the way you build things for your children — carefully, transparently, and to last.

Is there telemetry? What data do you collect?

None and none. The OS makes no network connections you didn't configure; svpkg sync talks to the mirror you chose, and mirror logs are standard web-server logs under each sponsor's own policy. Even the download counter on this site is just mirror log grep.

How do I report a security issue?

GPG-encrypted mail to security@longervision.us (key on the download page). Advisories go out on the announce list and land in svpkg up, usually within 72 hours for kernel/glibc/openssl-class issues.
