Current status

Fruix currently has:

• declarative system modeling on FreeBSD
• content-addressed system closures under /frx/store
• native FreeBSD base artifacts in /frx/store
• declarative FreeBSD source objects and source materialization
• source-driven native base builds from materialized source snapshots
• side-by-side source revisions and boot validation
• a host-driven non-interactive install path:
  • fruix system install
• a bootable Fruix-managed installer environment:
  • fruix system installer
• a bootable Fruix-managed installer ISO:
  • fruix system installer-iso
• an explicit installed-system generation layout under:
  • /var/lib/fruix/system
• explicit installed-system retention roots under:
  • /frx/var/fruix/gcroots
• a validated installed-system generation switch/rollback workflow via:
  • fruix system status
  • fruix system switch
  • fruix system rollback

Validated boot modes still are:

• freebsd-init+rc.d-shepherd
• shepherd-pid1

The validated Phase 18 installation work currently uses:

• freebsd-init+rc.d-shepherd

Latest completed achievement

2026-04-04 — Phase 19.3 completed

Fruix now has a validated installed-system operator workflow for switching to a staged candidate generation and rolling back to the recorded previous generation.

Highlights:

• installed systems now ship an in-guest Fruix deployment helper at:
  • /usr/local/bin/fruix
• validated in-guest command surface:
  • fruix system status
  • fruix system switch /frx/store/...-fruix-system-...
  • fruix system rollback
• switching now records explicit rollback state under:
  • /var/lib/fruix/system/rollback
  • /var/lib/fruix/system/rollback-generation
• switching now records explicit rollback GC roots under:
  • /frx/var/fruix/gcroots/rollback-system
• the validated installed-system workflow now supports:
  • stage candidate closure in /frx/store
  • switch to generation 2
  • reboot into the candidate
  • rollback to generation 1
  • reboot into the restored current system

Validation:

• PASS phase19-installed-system-rollback-qemu
• regression re-checks:
  • PASS phase19-generation-layout-qemu
  • PASS phase18-installer-iso

Recent major milestones

• 1d00907 — Add Fruix bootable installer environment
• 2517710 — Add non-interactive Fruix installation flow
• 02a02e3 — Document Fruix FreeBSD source policy
• 865012e — Boot Fruix from distinct FreeBSD source revisions
• 8150508 — Validate side-by-side FreeBSD source revisions
• 5cbf5b9 — Build native bases from materialized FreeBSD sources

Active constraints

• local bhyve remains blocked under Xen due to lack of nested VT-x exposure
• XO self-service creation is still not usable with the current token
• real XCP-ng validation must continue to use:
  • VM 90490f2e-e8fc-4b7a-388e-5c26f0157289
  • approved A/B VDIs:
    • 0f1f90d3-48ca-4fa2-91d8-fc6339b95743
    • 7061d761-3639-4bec-87f7-2ba1af924eaa
• local QEMU/TCG validation keeps conservative default SMP settings; QEMU_SMP remains overrideable

Next step

Per docs/PLAN_4.md, the next planned step is:

• Phase 20.1 — validate a Fruix-managed development environment for native FreeBSD base work

Phase 19.3 is now complete: Fruix validates installed-system generation switching and rollback through the intended operator-facing workflow.
