 1. Create a tarball of the built kernel:
 ```bash
-tar -czf custom-kernel.tar.gz -C result .
+mkdir result-writable
+cp -rL result/lib/modules/6.6.63/kernel result-writable/kernel
+sudo chmod -R u+rwX,g+rwX,o+rX result-writable
+tar -czf custom-kernel.tar.gz -C result-writable .
+rm -rf result-writable
 ```
 
-2. Upload the tarball as an artifact to Gitea:
-```bash
-curl -X POST -H "Content-Type: application/octet-stream" \
-     -H "Authorization: token YOUR_GITEA_TOKEN" \
-     --data-binary @custom-kernel.tar.gz \
-     "https://gitea.example.com/api/v1/repos/your-username/your-repo/releases/YOUR_RELEASE_ID/assets?name=custom-kernel.tar.gz"
-```
+2. Create a new release on Gitea and upload the tarball
