Introduction

The latest Synology pat files cannot be extracted using the tar command anymore and require special handling.

Based on https://github.com/pocopico/tinycore-redpill.

How to use

Git clone this repository.

git clone https://github.com/technorabilia/syno-extract-system-patch.git

Build the image.

cd syno-extract-system-patch
sudo docker build --tag syno-extract-system-patch .

Place the pat file you want to extract in ~/data/in.

$ ls ~/data/in
DSM_DS723+_42962.pat
$

Execute the following command.

sudo docker run --rm -v ~/data:/data syno-extract-system-patch \
  /data/in/DSM_DS723+_42962.pat \
  /data/out/.

The extracted pat file will be in ~/data/out.

$ ls ~/data/out
