I built the lite repository and got an error depending on which
original repo I used to push the lite one. Here is the history:

--------------------------------------------------------------
#
# building my pub repo from the "lite" repository
#

$ git checkout -b lite

$ git-show-branch
* [lite] Merge with Linux 2.6.14.
 ! [master] Merge with Linux 2.6.14.
  ! [origin] Merge with db93a82fa9d8b4d6e31c227922eaae829253bb88.

It seems that the "lite" repository can't be used as a working
repository. And If I use the last method to push some work, I can only
pull that changes from a full repository. From a lite one (without any
changes of course) I get this error:

Do you have any clues ?
