iocage_legacy basejails are created by cloning a dataset for each basejail_dir from /iocage/base/<RELEASE>/<BASEJAIL_DIR> into the jail. Due to performance reasons and the additionally created ZFS datasets this method was replaced by NullFS mounts in python-iocage.
Compatibility with iocage_legacy requires the ZFS release bases to be updated on each release modification, which doubles the required space and also slows down release operations.
Users who require this feature may enable it in /etc/rc.conf:
