*Shell changes - The default shell,/bin/sh,is now linked to ksh93. The default user shell is the Bourne-again (bash) shell.
*The legacy Bourne shell is available as /usr/sunos/bin/sh.
*The legacy ksh88 is available as /usr/sunos/bin/ksh from the shell/ksh88 package.
*Korn shell compatibility information is available in /usr/share/doc/ksh/COMPATIBILITY.

Example: Encrypting a ZFS File System by Using a Raw Key
In the following example, an aes-256-ccm encryption key is generated by using the pktool command and is written to a file, /cindykey.file.
# pktool genkey keystore=file outkey=/cindykey.file keytype=aes keylen=256 Then, the /cindykey.file is specified when the tank/home/cindy file system is created.
# zfs create -o encryption=aes-256-ccm -o keysource=raw, file:///cindykey.file tank/home/cindys
