error 1 is EPERM. Seems it needs --privileged on the container startup
as a podman argument (before the image name). Sorry I missed that

Taking https://packages.debian.org/bookworm/mariadb-server-core-10.6 package:
mariadb-install-db --no-defaults --datadir=/empty/btrfs/path
--innodb-use-native-aio=0
mariadbd --no-defaults --datadir=/empty/btrfs/path --innodb-use-native-aio=1
should achieve the same thing.
