I am trying to make use of the kernel overlayfs inside of an unprivileged container.
The rootfs of the container is an idmapped mount but that prevents overlayfs from working.
overlayfs: idmapped layers are currently not supported
I am aware that will be allowed in kernel 5.19 but for now, I would like to make this container chown the rootfs.
Is there any setting that can be used to disable idmapped mount for the rootfs (force Remapping container filesystem (chown) on idmap capable storage like btrfs).
