Installing ZFS on 9.0-RC2

[Mike Clarke]

I'm planning to upgrade to 9.0 soon and thought this might be a good 
opportunity to switch over to ZFS so I'm currently experimenting on a 
spare drive with the 9.0-RC2 DVD.

I started off following the procedure in 
http://wiki.freebsd.org/RootOnZFS/GPTZFSBoot but hit a problem in that 
the the new installer doesn't appear to provide a Fixit option. I've 
tried the shell and live cd options in the installer and also tried 
booting single user from the DVD but these all use the DVD as a read 
only root file system instead of the memory based file system in Fixit 
mode.

I was able to get as far as creating a zpool but the first zfs create 
comand produced an error saying that it was unable to mount zroot/tmp.

What's the correct approach to go about this with the 9.0-RC2 installer?
