How do I set the zpool/zfs version during installation of Solaris (or one of its derivatives)? Want to make sure that root/boot (& other pools) are all created at v28 & not upgraded to the latest version, so they can be accessible from older versions of OpenSolaris or one of its descendants.

P.S. I should also add that both zpool & zfs commands are unavailable, during Live-x86 (GUI/console) & text-x86 (console) installs!
 
What about installing with an older version and then upgrading to the latest, your pools will then be using the old zpool/zfs version.
 
The problem with this is having to upgrade the entire OS will break some things, a clean install is always desirable. Also upgrading between various flavors of Solaris is also a no go (between Solaris, Solaris Express, OpenIndiana, Nexenta or FreeBSD).

If I want a stable, updated/patched system with (almost) up to date hardware support, Solaris is the way to go; who knows if/when OI is going to be updated again, while FreeBSD has a long update cycle too (not to mention hardware support is always behind by a few years).
 
Do you really need your root pool to be with the old version if not. Then just create your data pool with the version you want (using an old OS version if thats the only way) but have the root pool using the latest version.

I hear you regarding upgrading. Stupid solaris 11 express -> solaris 11 broke the lp user used by cups-lpd and the inetd, somehow the /usr/spool/lp directory vanished. fixed now.
 
Yep, I do not really understand why you want your root pool to be compatible with other ZFS OS flavors, since no actual useful data is supposed to be stored in it.
And if you switch to OI, FreeBSD or whatever, you will have to reinstall root, so what is the point?

For the sake of it, for the data pool, the command is zpool create -o version=28 tank ...
