> Recent work enables the creation of ZFS images by makefs. This makes it easier to build ZFS-based VM images. makefs' ZFS support includes the ability to create multiple datasets, with each mapped to a directory in the input file hierarchy. Many ZFS features are not supported however, as the implementation provides only what is needed to get reproducible root pools.
Is ZFS aware of the FreeBSD Page Cache to avoid double buffering in ARC/L2ARC ? Or is it planned for future release ?
