zfs in production?

Yes. In fact amd64 is preferred.

If you do not intend to use ZFS for the root file system or similar,
you can just install as usual making sure to reserve space/drives as
appropriate. Then begin using ZFS after upgrading to -CURRENT.

If you want root-on-ZFS you'll have to either install one one device
and then do some acrobatics to convert the root file system, or boot
from some external media and perform a more custom installation (e.g.,
install a modern -CURRENT on a USB stick, then use 'make
installworld', 'make distribution' etc to set up your system like you
would a jail).

Note that you will loose some functionality (self-healing) if using
ZFS on hardware RAID.
