The IO through fuse-overlay is performance limiting though. It's almost half the speed as overlay directly for layers with many tiny files.

Note that Linux allows you to mount overlay within a user namespace if you are root within the user namespace.

In other words, if you are root within a container; even though it is not root on the host; Linux accepte ton mount overlay filesystems (most filesystems are not allowed). `man user_namespace`

You may need to do

  podman system reset

The Linux kernel only gained unprivileged overlay recently. Kernel fuse and fuse-overlay are incompatible so you need to wipe everything.

You may need to set

  [storage]
  
  driver = "overlay"

in storage conf as well.
