[gentoo-user] howto on setting up rootfs on ZFS?

I used the existing wiki to get ZFS up and running on my system a few weeks
ago and after getting familiar with it, beating it up a bit, and breaking
it in as many different ways as I could envision, I think I'm happy with
it. I'd now like to use it as my rootfs. I'm going to leave /boot as a
separate extX filesystem for simplicity's sake. I can't find any decent
Gentoo-related documentation on setting up rootfs on ZFS. I'm not even sure
what boot media supports ZFS (system rescue cd doesn't, and my googling
turns up a bunch of *bsd based media).

Anyone done this before and care to help a brotha out?

Look at the modules link on the Rescue CD pages, it has a link to a ZFS
module file. This includes a script to rebuild the ISO including the ZFS
modules, I've used it several times with success, the only thing the
documentation fails to mention is that after booting the CD, you have to
run "depmod -a" before you can use the ZFS modules.

Hi, 

I use grml livecd for various recovery/livecd purposes. I just
add an script to my boot partition to compile current zfs. Since it is
debian based it contains installation through aptitude. 

Robert.

/boot/zfs # ls
install_zfs*  spl-0.6.1.tar.gz  zfs_create  zfs-0.6.1.tar.gz

/boot/zfs # cat install_zfs
#!/bin/sh

aptitude update
aptitude install build-essential zlib1g-dev uuid-dev
aptitude install linux-headers-3.7-1-grml-amd64 

tar -xvzpf spl-0.6.1.tar.gz
tar -xvzpf zfs-0.6.1.tar.gz

cd spl-0.6.1
./configure --prefix=/
make
make install

cd ..
cd zfs-0.6.1
./configure --prefix=/
make 
make install

cd ..

rm -rf zfs-0.6.1
rm -rf spl-0.6.1
