Hi,


Just a note that when you run git-describe, you should probably quiten it.

fatal: cannot describe 'bd7364a0fd5a4a2878fe4a224be1b142a4e6698e'

This happens when tags are not present, which can happen if Linus's tree
is sent upwards again, IOW:

machine1$ git-clone torvalds/linux-2.6.git
machine1$ git push elsewhere master

machine2$ git-clone elsewhere:/linux
machine2$ git-describe HEAD
fatal: cannot describe that

Hi Jan.

Any specific reason why you sent it to me?
Maybe because I do not use git describe at all?

Maybe he was thinking about this (and didn't know that you were moving):

You are the buildsystem maintainer :)

I only took note of that briefly. Should there have been someone
else to send it to?

I just failed to see the connection to kbuild - I had long
forgotten that we uses git describe in setlocalversion script.
