I have been on this list for only a few days now, so I don't know anything
about these growfs patches. But I'll guess I can find them somewhere. Unless
they're scattered all over the place ;-)

I run 6.2-RELEASE by the way. What's the easiest way to get the right growfs
version with the necessary patches?

growfs scares me more than gpt destroy :)

Meddling with a FS that has data on it is always scary, no matter what tools
you use. But your detailed description helps a lot. So once I updated growfs
I'll try this approach myself.

Best regards,
