+### Enabling Talos system extensions
+
+I wanted to deploy Longhorn on a Talos cluster and I didn't realise that at the time I didn't include the required extensions:
+
+- siderolabs/iscsi-tools
+- siderolabs/util-linux-tools
+
+After a bit of struggling, I found the fix on Reddit lol... create a patch file:
+
+```
+# patch.yaml
+
+customization:
+  systemExtensions:
+    officialExtensions:
+      - siderolabs/iscsi-tools
+      - siderolabs/util-linux-tools
+```
+
+Use this patch file in a POST request to the Talos image builder to get the schematic ID for an image with these extensions:
+
+```
+curl -X POST --data-binary @patch.yaml https://factory.talos.dev/schematics
+
+# OUTPUT:
+{"id":"613e1592b2da41ae5e265e8789429f22e121aab91cb4deb6bc3c0b6262961245"}
+
+```
+
+Then upgrade the Talos cluster using this new schematic (make sure to match the version of Talos software that is currently running - in my case it was 1.11.5):
+
+```
+talosctl upgrade --preserve --image factory.talos.dev/installer/613e1592b2da41ae5e265e8789429f22e121aab91cb4deb6bc3c0b6262961245:v1.11.5 --nodes=192.168.0.5,192.168.0.6,192.168.0.7,192.168.0.8
+
+# OUTPUT:
+watching nodes: [192.168.0.5 192.168.0.6 192.168.0.7 192.168.0.8]
