 description: How to create custom ext2 images to use as a filesystem for CheerpX

-This guide demonstrates how to create a custom `ext2` image for use with CheerpX while ensuring that the root ownership of files is maintained.
+This guide will show you how to configure a Docker container and build it into an `ext2` image for use with CheerpX.

+Create a directory for the filesystem:
 
 ```bash
 mkdir cheerpXFS
 ```
 
-Now copy the files from the container into the directory. This should preserve root ownership when executed from within a root user environment.
+Use the podman cp command to copy the container’s filesystem into the local directory:
 
 ```bash
-podman cp cheerpxcontainer:/ cheerpXFS/
+podman unshare podman cp cheerpxcontainer:/ cheerpXFS/
 ```
 
-If you are running `podman cp` as a non-root user and face any issues with permissions, you might need to adjust the directory ownership after the copy by using `chown`:
-
-```bash
-sudo chown -R root:root cheerpXFS
-```
-
-This step will ensure that the files in the local `cheerpXFS` directory are owned by `root`.
+> [!note] Note
+> The podman unshare command helps avoid permission problems by running the operation in a special mode where you act like the container's "root user."
