zpool on a zvol inside zpool

[Eugene M. Zheganin]

Hi.

I'm moving some of my geli installation to a new machine. On an old
machine it was running UFS. I use ZFS on a new machine, but I don't have
an encrypted main pool (and I don't want to), so I'm kinda considering a
way where I will make a zpool on a zvol encrypted by geli. Would it be
completely insane (should I use UFS instead ?) or would it be still
valid  ?

Thanks.
Eugene.
