With some help from Matt Connolly, and reference back to an earlier exchange on
OI-Discuss last November/December ("livecd zpool import -fR /a xpool but no
files") I have got to the following:
jack@opensolaris:~$ pfexec zpool import
pool: rpool

action: The pool can be imported using its name or numeric identifier.

jack@opensolaris:~$ pfexec reboot -f
Failed to process GRUB menu entry for fast reboot, no
such entry found
Falling back to regular reboot.
System then continues as though it had just been powered up, but after the BIOS
screens it halts at a black screen with GRUB_ in the top left hand corner. The
only possible action then is to switch off. So there is no fast reboot in the
USB live image (of OI-147).
Obviously I am missing something here (probably quite a lot) but I don't see
what to try next. If anything looks wrong in the above, or any suggestions as
how to boot 0i_148-2 please tell me!

Thanks Matt - you've put your finger on the problem. I have no /a/boot/grub !
I'd noticed that the live USB image has /boot/grub with the entries you
identify. I wasn't sure what to make of that.
I don't really get your line
"exchanging PATH for the mount path to what was the active boot environment,
not just the root of the pool."
what was the active boot environment ? How do I discover that ?
Cheers
Guy

On my system, I
see:
matt@vault:/opensolaris/boot/grub$ ls /rpool/boot/grub/
bootsign capability menu.lst splash.xpm.gz
and
matt@vault:/opensolaris/boot/grub$ ls /boot/grub/
bin e2fs_stage1_5 install_menu menu.lst
pxegrub stage1 ufs_stage1_5 xfs_stage1_5
capability fat_stage1_5
iso9660_stage1_5 minix_stage1_5 reiserfs_stage1_5 stage2
ufs2_stage1_5 zfs_stage1_5
default ffs_stage1_5 jfs_stage1_5 nbgrub
splash.xpm.gz stage2_eltorito vstafs_stage1_5
There's definitely more files in /boot/grub in the active boot environment than
there is in /rpool/boot/grub.
Perhaps you can boot off the live disc, and
# installgrub PATH/boot/grub/stage1 PATH/boot/grub/stage2 /dev/rdsk/c0t1d0s0
exchanging PATH for the mount path to what was the active boot environment, not
just the root of the pool.
I checked on my machine if I `beadm mount be_name mount_point` then in
`/mount_point/boot/grub/' I see the full list of boot files.
The only thing I'm not sure about is how `beadm mount` goes at mounting boot
environments from another pool.
Hope that helps somewhat,
Matt
