    Hmm, I'd still be very reluctant to use ZFS in such a manner. While its holding
    out pretty well on Solaris Express so far its still harder to "fail safe" than
    your regular UFS filesystem.

    Its relatively easy to mount ZFS from a rescue system (like you get when
    booting from the install cd) but it can be a little tedious to set it all up
    since its not an issue of simply mounting the filesystem and be done with it.

    Personally I'd always keep / installed on UFS. Simply because it makes it
    easier to boot, the data is normally quite static anyway (so really not much
    need for variable space allocation) and when something does go wrong its easier
    to access. You might even be able to boot from the cd and then use the cd to
    boot your regular installed os.


    My preferred installation so far is putting / and /var on UFS and then creating
    one huge slice for the ZFS pool.

    you are right failsafe is no option.
    boot and stop is what i use then force mount root -rw.

    Tabriz installation is creating a "dualroot".
    the original root is available.

    absolutly agree, nv is beta software and so is zfs until June.
    Tabriz has done some clever "hacking"
    now im using compression on the root file sys,
    just for the fun of trying :-)
