No, our procedure is to use --link.

We generally don't use "in place" OS upgrades - however we would
usually have the databases on separate filesystem(s) to the OS, and
those filesystem(s) would be preserved through the upgrade, while the
root fs would be scratched.
A lot of the cases reported are on RL8. I will try to find out the
history of the RL9 cases to see if the filesystems started on RL8.
Could you please provide me links for the kernel bugs you are referring to?
Cheers
Mike.
