Installing FreeBSD on ZFS with Windows

[Christian Baer]

Good evening all!

I'd like to install FreeBSD on a machine that already runs Windows in a 
dual-boot setup. This works find when using UFS for /, /var and /usr. 
However, I'd like to install FreeBSD on ZFS. Well, I could live with a 
separate / with UFS and the rest being on ZFS.

The BSD installer doesn't offer this functionality and I have never done 
this before, so I'd like a guideline to how this is done. The handbook 
does state that I could accomplish this via the shell, but does not say 
how this is done.

Is there a useful howto out there on how to accomplish the task at hand 
or is this generally a bad idea?

Note: The medium I'd like to install FreeBSD on is an SSD.

Best regards,
Chris
