Explanation
A: ZFS encryption was introduced in ZFS Pool Version Number 30, Solaris Nevada b149. Filesystem encryption since Solaris 11 Express B: Deduplication was introduced in ZFS Pool Version Number 21, Solaris Nevada b128. E: Booting From a ZFS Root File System Both SPARC based and x86 based systems use the new style of booting with a boot archive, which is a file system image that contains the files required for booting. When a system is booted from a ZFS root file system, the path names of both the boot archive and the kernel file are resolved in the root file system that is selected for booting.
