Why is there no git repository after installing etckeeper?

Question 1

I installed etckeeper on my ubuntu 11.10 server, and after creating the etckeeper repository with:

etckeeper init
etckeeper commit "Initial version"

I got the error:

bzr: ERROR: No changes to commit. Please 'bzr add' the files you want to commit, or use --unchanged to force an empty commit.

So I added a test file and then I could create the etckeeper repository:

touch /etc/test
etckeeper commit "Initial version"
rm /etc/test

But still there seems to be no git repository there:

cd /etc
git status

How can I use git to watch changes?

Question 2

I found out:

in the config-file etckeeper/etckeeper.conf You have to set

VCS="git"
#VCS="bzr"

then again:

etckeeper init
etckeeper commit "Initial version"

Then everything works on git:

cd /etc
git status
