Just to follow up for anyone who might be looking for info about this at
sometime or another - my full onnv build failed, but the grub portion
of it built fine. So, here's what I did:
1) Did a 'make install' in my onnv-gate/usr/src/grub directory. This
put the stage1 and stage2 files in my
onnv-gate/proto/root_i386/boot/grub directory.
2) Determined which specific drive I was booting from:
$ zpool status rpool
pool: rpool
state: ONLINE
scrub: none requested
config:
NAME STATE READ WRITE CKSUM
rpool ONLINE 0 0 0
c7t1d0s0 ONLINE 0 0 0
3) Installed my new stage1 and stage2 files while sitting in my
onnv-gate/proto/root_i386/boot/grub directory. Note that I also
modified the grub_printf "GNU GRUB version" line in char_io.c: line to
make sure my custom grub made it onto the disk:
$ pfexec installgrub stage1 stage2 /dev/rdsk/c7t1d0s0
Worked like a charm.
