As I've said in an earlier thread, I'm a bit skeptical of ZFS and it's
claims... but I ran across this quote from the Wiki entry that seems to
be a rather hefty red flag:

"ZFS is currently not available as a root filesystem since there is no
ZFS boot support, Sun plan to add this feature in late 2006."

Then there's:

"Sun has said it is investigating the porting of ZFS to Linux but this
is complicated by the incompatibility between the OpenSolaris license
CDDL and the GPL which governs the Linux kernel."

So don't expect the linux kernel to support it.  Unless Sun changes the
license, it will never enter the kernel.  The current "Google Summer of
Code" project is to get ZFS running under FUSE, so it will only run in
userspace...

In terms of ZFS, the operative phrase is "Don't hold your breath."
Maybe, someday, it'll be ready, but not any time soon... there's a long
way from "We've jury-rigged it to run through FUSE", and "I'll trust it
with my critical data."
