ADVfs uses the free list within the FS (actually within the file domain). This _does_ mean that clonefset doesn't work on very full, dynamic filesystems. The upside is that it works most of the time and doesn't require reserved free disk space. If there's no free space left, a kernel error message is generated warning that the clone filesystem is no longer consistent (but I don't think it actually inhibits access to it).
