Hello,
Why, hello to you too.
Can you explain what problem you are trying to solve?
Presumably if someone has set the personality, they had a reason for
doing so. On what grounds do you think it is a good idea to override
the explicit desires of the user and restore a default personality?
This patch would break many software build systems.
Unless you can explain why this is needed, I have to say:
NAK to this patch.
Thanks,
David Daney
