Pcbsd 9.1 beta1 64 bits

Hi,

Some questions about PCBSD 9.1 BETA1...

First : My computer :
1 ssd with PCBSD 9 and upgraded to PCBSD 9.1 BETA1
a ZFS raid mirror ( 3 hdd) that i have imported (zfs import -a) in /stockage

I have seen on http://blog.pcbsd.org/
article 9.1-BETA1 Now Available

Highlights for the upcoming 9.1-Release:
"allowing entire disk ZFS installation."
That said i will be able to install PCBSD + my /stockage only on the 3 hdd, without the SSD ?

How to migrate on this configuration?

If i have PCBSD + /stockage on the 3 hdd only, and if PCBSD crash,
How to re install all without lost data on my /stockage?

An other question :
If i have PCBSD + /stockage on the 3 hdd only.
If the update manager says i can upgrade it. Can i do a snapshot of all my system ( / ) and if the upgrade don't satisfy me, how to back into the last snapshot?

A sub question : if the upgrade crash my system (PCBSD can not boot correctly), how to back to the last snapshot? With a live dvd of PCBSD ?


One other question: Warden .
I 've created some jails with PCBSD 9 and Warden PBI.
With the PCBSD 9.1 BETA update, i have 2 warden software now : the pbi software, and the "native" software.
The pbi software is compatible with my jails created before.
The "native" software is not compatible.
How to upgrade my PCBSD 9 jail into PCBSD 9.1 ?

Must i have to recreate all my jail?

Thanks for all,
and thanks to offer PCBSD
