Don't do that -- the information in the Wiki is a bit outdated now.
Instead, just use the installer to setup a ZFS system for you.  This
will build you a system set up for use with boot environments etc. etc.

There aren't any specific tunings to apply for poudriere (at least, not
that I'm aware of) -- the workload is reading and writing files of a
mixture of sizes during compilation which is pretty much the default
that ZFS is designed around.

You will (counter intuitively) need to limit the amount of memory ZFS
will allocate to ARC -- you want to make sure there's a good chunk of
RAM left free for the compilers to use.
