ZFS NAS configuration question

[Dan Naumov]

This reminds me. I was reading the release and upgrade notes of OpenSolaris
2009.6 and noted one thing about upgrading from a previous version to the
new one::

When you pick the "upgrade OS" option in the OpenSolaris installer, it will
check if you are using a ZFS root partition and if you do, it intelligently
suggests to take a current snapshot of the root filesystem. After you finish
the upgrade and do a reboot, the boot menu offers you the option of booting
the new upgraded version of the OS or alternatively _booting from the
snapshot taken by the upgrade installation procedure_.

Reading that made me pause for a second and made me go "WOW", this is how
UNIX system upgrades should be done. Any hope of us lowly users ever seeing
something like this implemented in FreeBSD? :)
