Bootable ZFS is probably one of the hottest ZFS topics. Unfortunately ZFS filesystems cannot currently be used as your root filesystem, however help is on the way!
The ZFS Boot project has been tasked with providing boot and install support for ZFS filesystems. Last year they documented a way to activate ZFS Mountroot, a feature that was integrated in Solaris Nevada Build 37 and that gives you the capability of configuring a ZFS root filesystem. ZFS Mountroot is off by default, but have a look at the team's blog to learn how it can be switched on -- only if you're feeling adventurous: http://blogs.sun.com/tabriz/category/ZFS
Important Notes: Currently ZFS Mountroot only works on a x86/x64 machine and it's not a complete boot solution -- it relies on the existence of a small UFS boot environment to bootstrap the machine. Sun has talked about adding ZFS bootability to machines running on SPARC technology by teaching the SPARC OBP to utilize GRUB as a boot loader.
Hope this helps.
Q. Can we configure ZFS on the root (/) file system using Solaris 11/06?
