If the patch ever prevents middlewared from starting, users now have a clear escape hatch that requires no knowledge of Python internals: bash /data/truecloud-patch/recover.sh Or at a bare shell prompt: touch /data/truecloud-patch/disabled systemctl restart middlewared sitecustomize.py checks for /data/truecloud-patch/disabled at Python startup and skips the import hook entirely when the file exists. apply.sh does the same so the PREINIT script also does nothing on reboot. recover.sh is copied to /data/truecloud-patch/ by install.sh so it is available even without the original repo directory. README gains an "Emergency recovery" section above Troubleshooting.

# install.sh — run once on the TrueNAS box to set up truecloud-patch.
|
|
#
|
|
# Prerequisites: run as root on TrueNAS SCALE with middlewared running.
|
|
#
|
|
# What this does:
|
|
# 1. Copies patch files to /data/truecloud-patch/ (survives OS updates).
|
|
# 2. Registers a PREINIT initshutdownscript in the TrueNAS database so
|
|
# apply.sh re-applies the patches on every boot before middlewared starts.
|
|
# 3. Applies the patches immediately (no reboot required).
|
|
# 4. Restarts middlewared so the backend change takes effect now.
