Devin Teske and I have been working on a big patch to bsdinstall to
implement installing on a ZFS pool. It supports both GPT and MBR, the 4k
sector gnop trick, and optional GELI encryption. We would like to commit
this in time for 10.0-BETA1 so it needs some testing to work out any
obvious bugs before we send it off to re@ to get it committed.
It includes a single configuration menu that allows you to select all of
the required details, including which drives to use (gets details from
camcontrol, also includes an inspection utility that presents the
detailed output of camcontrol inquiry/identify, and gpart show), what
ZFS RAID level to use (taking in to consideration the selected number of
drives), GPT/mbr, 4k YES/no, GELI yes/NO, pool name, etc.
Additional, it includes some other changes to bsdinstall:
1. Change the default to the 'non-standard keyboard mapping' prompt to no
2. Replace the 3 separate dialogs to configure an ipv4 address with just 1
3. Remove the dialog asking if you wish to enable crash dumps, this
feature has been combined into the regular 'services to enable' dialog
and enabled by default
You can browse the patches here:

I've built a bootonly.iso (10.0-ALPHA4) to make testing easier,
available compressed (48 MB) or uncompressed (211 MB):

We look forward to your feedback
Thanks for doing this! I had a few comments:
1. ZFS is not bootable on all architectures. Could you adjust that menu
item to only display for i386, amd64, and (I think?) sparc64. Use uname
-m, not -p, for this.
1a. The script is broken on sparc64 in any case, which uses VTOC8
instead of GPT.
2. Why are you using camcontrol? That is guaranteed not to work on
non-CAM systems. You should use the GEOM ident string if you need an ID.
3. Any plans to integrate this into the regular partition editor? ZFS
support is important enough that I will definitely not get in the way,
even as a bolt-on, but it would be a shame for it to stay that way. The
editor is also designed for ZFS to be added.
4. What is this gnop stuff for?
5. I think some substantial part of the MBR code will blow up if you are
reinitalizing a previously formatted disk (the bsdlabel will be retasted
and come back from the dead).

I wrote some support for adding ZFS to the partition editor a couple of
months ago, around the time that 9.2 was branched. One of the biggest
things that I have not done is integrate setting up a zfs mirror between
any disks before creating the zpool. Nor did I do the gnop hack to
create 4K disk blocks before creating the pool.
I more or less changed the partedit program to take an argument when
invoked with "ufs" (same as current behavior) or "zfs", which knows
about zfs setup stuff. The hookup to the actual scripts was, shall
we say, much less intrusive than what has been published here.
I guess it's time to dig out the patches and make them available to
others.
