SageOS v5.1 — First Stable Release 🎉

After 10 beta iterations, all core issues are resolved and confirmed working end-to-end — including a real-world confirmation booting in VirtualBox (not just QEMU) by the project owner.

What's fixed since the beta line

  • Networking: e1000/e1000e/pcnet32 drivers + dhclient integration — DHCP + DNS work out of the box in both QEMU and VirtualBox.
  • Package management: fixed sudo's missing setuid bit and a /dev/null permissions bug (caused by a second mdev -s scan silently resetting devtmpfs defaults) that broke apt-key/gpgv verification — apt update and sage-pkg install now work cleanly.
  • ping: fixed missing cap_net_raw capability so regular (non-root) users can ping.
  • OS branding: /etc/os-release and fastfetch now correctly report SageOS 5.1 instead of the underlying Debian version.
  • Init system: migrated from a custom busybox PID 1 script to OpenRC for proper dependency-based service management.
  • Persistence: sage-persistence-setup reliably formats a second disk for a writable overlay that survives reboots (mke2fs -F -F fix for devices flagged in-use).
  • Boot performance: squashfs is copied into RAM at boot when sufficient memory is available, avoiding slow repeated reads from emulated optical drives (major VirtualBox speedup).

Architecture

SageOS follows a lean, install-on-demand design: the base ISO ships with only the Active Directory mission pack pre-installed (~230MB). Every other security-tool category (networking, web, password, wireless, sniffing, forensics) installs on demand via sage-pkg install <category> or the sage-security whiptail menu — keeping the base image lightweight.
