[OpenIndiana-discuss] How to replace a motherboard without reinstalling OpenIndiana

[Robin Axelsson]

That was an interesting link. I wonder if these steps really are 
necessary. It sure doesn't hurt to make a backup copy of 
/etc/path_to_inst but creating an empty "reconfigure" file at the root 
seems to be enough.

To describe the instructions in the "bug-report" in words:
(preparatory steps)
1. Boot using OSOL/OI LiveCD
2. Locate and mount the rpool of the system (zpool import -f rpool)
3. Locate and mount all the other pools as well (zpool import -f 
<otherpools> - found using zpool list)
4. Locate and mount the boot environment into a suitable subdir under 
root (beadm list; beadm mount opensolaris-n /subdir)
5. Move the path_to_inst and create a new empty one (mv 
/subdir/etc/path_to_inst <another path>; touch /subdir/etc/path_to_inst)

(the actual modification procedure)
6. Clean and rebuild the device tree (devfsadm -C -r /subdir)
7. Clean and rebuild the device tree for disks only (devfsadm -c disk -r 
/subdir) - is this really necessary??? Isn't that done in step 6 already?
8. Copy the actual zfs cache to the rpool (cp /etc/zfs/zpool.cache 
/subdir/etc/zfs/zpool.cache)
9. Force a reconfiguration upon next boot (touch /subdir/reconfigure) - 
pretty much as suggested by Tim Bell on this mailing list
10. Recreate the boot-archive (bootadm update-archive -R /subdir)
11: Run cd /; sync; sync; sync;  - what's this for, and why run "sync" 
THREE times?
12. VERY IMPORTANT STEP!!: Unmount the "opensolaris-n" boot environment 
using the beadm command (beadm unmount opensolaris-n)

(reboot)
13. Reboot using e.g. init 6 and on next boot select in LiveCD grub menu 
"boot from hard drive" - Wouldn't it be easier to just remove the LiveCD 
before reboot?

I'm not sure why all these steps would be necessary as they should be 
taken care of automatically when forcing a "reconfigure" in first place. 
Thanks for your post!

Robin.
