The "Automated releases" entry was written under v0.3.0, but that commit landed after the v0.3.0 tag -- the CHANGELOG was claiming the release contained something it did not. Moved to its own version rather than left as a quiet inaccuracy. Bumps VERSION to 0.3.1 across all four scripts, which the new consistency check now enforces.

# recover.sh — emergency recovery if middlewared won't start after installing truecloud-patch.
|
|
#
|
|
# Run this from the TrueNAS shell (local console, SSH, or debug shell):
|
|
#
|
|
# bash /mnt/tank/truenas-truecloud-patch/recover.sh
|
|
#
|
|
# What it does:
|
|
# 1. Creates a "disabled" file in the repo root — apply.sh checks for this
|
|
# file at boot and skips all patching, so the next boot is always clean.
|
|
# 2. Unmounts any active truecloud overlays so the original /usr files are
|
|
# visible immediately (no reboot required).
|
|
# 3. Restarts middlewared against the unpatched files.
|
|
#
|
|
# To re-enable the patch after investigating:
|
|
# rm /mnt/tank/truenas-truecloud-patch/disabled
|
|
# bash /mnt/tank/truenas-truecloud-patch/patch/apply.sh
|
|
# systemctl restart middlewared
