flan ee190f558f Fix PREINIT 10-second timeout killing apply.sh before patches land 
Registers the boot hook with timeout:120 so TrueNAS gives apply.sh
two minutes instead of the default ten seconds.  Also consolidates
apply.sh Python subprocess count from ~8 to 2, cutting startup
overhead from ~12-16s to ~2-4s.

Bumps all scripts to v0.0.3.

Changelog

v0.0.3 — 2026-06-22

Fixed

  • patch/apply.sh silently killed by the 10-second PREINIT timeout. TrueNAS PREINIT initshutdownscripts have a 10-second default timeout. The previous apply.sh ran approximately 8 Python subprocesses (each ~1-2 s), so it was routinely killed mid-run. Symptoms: patches not applied after reboot, but re-running bash apply.sh manually (no timeout) always succeeded.

    Fix: install.sh now registers the hook with "timeout": 120. Existing installations are updated to the new timeout on the next bash install.sh run.

    Additionally, patch/apply.sh consolidates its Python subprocess invocations from ~8 down to 2, reducing startup overhead from ~12-16 s to ~2-4 s — well within the new 120-second budget.

Changed

  • find_mw_python in apply.sh no longer spawns a separate Python process to verify the interpreter can import middlewared. Verification is now implicit in the combined path-discovery subprocess that follows.

v0.0.2 — 2026-06-19

Fixed

  • B2 backup failing with NotImplementedError after a TrueNAS update. The patch block's guard (if "get_restic_config" not in B2RcloneRemote.__dict__) could misfire and silently skip injecting the method — most likely when a TrueNAS version adds a stub that raises NotImplementedError, causing the dict check to return False. The guard is removed; the assignment is now unconditional. This is safe because the native-support kill switch already prevents patching when TrueNAS ships a real, working implementation.

  • Native-support check falsely triggering kill switch on stubs. The check now inspects the source of any pre-existing get_restic_config before concluding that TrueNAS has shipped native B2 support. If the method body contains NotImplementedError it is treated as a stub and patching continues; only a method that does not raise NotImplementedError triggers the kill switch and auto-disable.

v0.0.1 — 2026-06-16

Initial public release. Extends TrueNAS SCALE's TrueCloud Backup feature to work with S3-compatible providers and native Backblaze B2 in addition to Storj, using volatile overlayfs patching of the TrueNAS middleware that persists across system updates via a PREINIT initshutdownscript.

Included

  • install.sh — registers the PREINIT boot hook and applies patches immediately
  • patch/apply.sh — PREINIT script; mounts writable overlays, patches b2.py and restic.py, patches the Angular UI bundle to widen the credential dropdown
  • patch/create_task.py — CLI to create TrueCloud Backup tasks with S3 or B2 credentials, bypassing the Storj-only restriction in the UI
  • recover.sh — emergency recovery; sets the kill switch and restarts middlewared
  • uninstall.sh — full removal of the patch and PREINIT hook
  • Kill switch support (disabled file) for safe degradation
  • Auto-disable when TrueNAS ships native B2 restic support
  • hook_status.json written on each boot for create_task.py verify
