The native-support check looked only for native B2 restic support and, on
finding it, set the kill switch and disabled the whole patch. That was fine when
providers were the only thing here. With nested-dataset snapshots in the patch it
is wrong: TrueNAS is likely to ship one capability long before the other, and a
single all-or-nothing kill switch would silently take a still-needed module down
with the superseded one.
apply.sh now treats the patch as two independent modules:
providers b2.py + restic.py + the UI credential dropdown
native when B2RcloneRemote carries a real get_restic_config()
nested plugins/cloud/{snapshot,crud}.py + cloud_backup/sync.py (opt-in)
native when the "no further nesting" validation is gone from
plugins/cloud/crud.py
Each is detected and skipped on its own. The kill switch fires only once BOTH are
done (native, or nested was never enabled). The UI patch belongs to providers and
is skipped with it. The deferred middlewared restart now fires when ANY
still-needed module landed -- keying it off providers alone would have left a
freshly-patched nested module on disk and never loaded on a native-B2 box.
hook_status.json reports each module with an active flag and a reason.
README: dropped the warning boxes and the disclaimer's fear-bulleting in favour
of plain statements, documented the two-module design and the per-module
auto-disable, and added a Development section disclosing AI assistance. The one
caveat kept, as a plain sentence rather than a banner: the mount --bind staging
step has not yet been exercised by a live backup run.
67 tests, ruff and shellcheck clean.

# patch/apply.sh — registered as a TrueNAS PREINIT initshutdownscript.
|
|
#
|
|
# PREINIT scripts are executed BY middlewared itself (ix-preinit.service runs
|
|
# `midclt call initshutdownscript.execute_init_tasks PREINIT`, ordered after
|
|
# ix-zfs.service pool import). So when this script runs at boot, middlewared
|
|
# is already up and has already imported the stock modules — the on-disk
|
|
# patch alone cannot reach the running process.
|
|
#
|
|
# TrueNAS updates replace /usr/ entirely; this script re-applies three patches:
|
|
#
|
|
# 1. Backend — b2.py and restic.py are patched directly in the overlay.
|
|
# On a boot run, a single detached middlewared restart is scheduled
|
|
# (Step 3) so the patched modules actually get loaded.
|
|
#
|
|
# 2. Nested-dataset snapshots — installs _truecloud_nested.py and patches
|
|
# plugins/cloud/{snapshot,crud}.py + plugins/cloud_backup/sync.py so the
|
|
# "Take Snapshot" option works on a dataset that has child datasets.
|
|
# Stock middleware refuses that config, because it points the backup tool
|
|
# at the PARENT's .zfs/snapshot/ where children are invisible — it would
|
|
# silently back up a near-empty tree. We stage a complete tree of
|
|
# per-dataset bind mounts and only then relax the guard.
|
|
#
|
|
# 3. Angular JS bundle — Widens the TrueCloud Backup credential dropdown
|
|
# from Storj-only to include S3 and B2. Served from
|
|
# disk per request, so no restart is needed for it.
|
|
#
|
|
