--- Comment #5 from Roberto Aguilar <r@rreboto.com> ---
I'm interested in the TPM2-based functionality in this patch and am curious if
it could be applied to supply the secret to ZFS root filesystem using native
encryption [1].

While it is possible to put ZFS on top of a GELI-encrypted filesystem, one of
the main reasons I'm looking to get native ZFS encryption is to be able to send
the encrypted filesystem over the wire to a remote system.  This would give me
offsite backups to a remote system that doesn't need to know the encryption
key.

Thanks!
