Where can I get the updated guides?

There''s nothing there about how to install ZFS boot systems from this
flag-day onward.

Also, the docs at http://opensolaris.org/os/community/zfs/boot/ don''t
mention that builds 86 and 87 are toxic for ZFS boot systems.

How would I install a ZFS boot system with these bits?

Looking at the CRs putback I think the procedure for installing ZFS boot
systems is still much as the old procedure, but modified to: swap and
dump on a zvol, and not to use legacy mounts.  Specific details would be
useful.

Also, will ZFS boot systems built with your bits upgrade correctly once
the install and Live Upgrade phase of ZFS boot delivers?  Or should one
wait before trying ZFS boot?

I''ve just tried to bfu my system from b87 (which was in turn
bfu''ed from OS DP 2, so has a ZFS root as installed by DP 2), and b88
is unbootable.  I retrieved the non-debug b88 bfu archives from the ON download
page, so am not using a local build.

I''m relatively new to debugging boot problems on Solaris, so
I''m not sure how to capture the full log, but the bits that I can grab
before the system automatically boots are:

spa_import_rpool: error 22
cannot mount root path /ramdisk:a.

I''ve reverted my rpool to the ZFS snapshot I took before upgrading to
b87 and bfu''ed again, with the same result.

I''m assuming this has something to do with the changes to ZFS boot
and/or Grub.  Am I supposed to be reinstalling Grub to the boot block, or does
BFU handle this automatically?  I haven''t modified /etc/vfstab or the
properties on rpool/ROOT/preview2, so it''s still set to a legacy mount
point.  Do I need to do a zpool upgrade from the bfu prompt?
