How to modify rootless container's files by using podman mount?

[kasraghu]

Hello,
I am trying to edit files of a rootless container from host (podman version 4.6.2 on Debian Trixie).

I have run podman unshare and podman mount ContainerID. The container filesystem is available on host ~/.local/share/containers/storage/vfs/dir/0123. I have added file at ~/.local/share/containers/storage/vfs/dir/0123 on host but, this file is not available inside the container.

If I do podman cp test.txt ContainerID:/test, the file is available on the container. What should I do to use the mount option properly?

First start using overlayfs not vfs for the storage layer.
