This release brings support for native ZoL encryption! It supports encryption on the entire pool, or enabled for a specific boot environment!
Prompting for the passphrase happens if the key needs to be loaded to boot the environment set in bootfs or if you escape the auto-boot screen to enter the environment/snapshot/kernel browser.
A patch is provided for 90zfs/mount-zfs.sh which detects if the keylocation is a file, and then attempts to load it from disk. If the key file is not present, and the type is passphrase, it will prompt.
The default auto-boot screen now attempts to center itself in your tty, for a slightly easier to read output.
Booting from a snapshot has been fixed - the snapshot is now correctly unmounted after a kernel/initramfs pair is located in /boot from the snapshot.
