-The boot partition is mounted with read-only permissions at ''/boot/'', but can be [[:edit_boot_partition#editing_the_boot_partition_while_batocera_is_running|remounted with write permissions post-boot]].

You do not need to save an overlay for file edits made in the boot partition, as this is a physical partition where your edits are permanent (and because of that, any edits you make here are more dangerous and can result in a non-booting machine, always make backups before attempting this). All the user data is stored in a separate userdata partition, which is mounted with write permissions at the path ''/userdata/'' (like the boot partition, this is just your regular userdata storage partition, no need to save overlays for this either).
