With git version 1.7.1.rc1.248.gcefbb and this script:

#!/bin/bash rm -rf a b c git init --bare b git clone b a cat > b/hooks/post-receive <<EOF #!/bin/bash # dummy EOF chmod +x b/hooks/post-receive cd a date > foo;git add foo; git commit -m foo; git push origin master

I get this output:
Initialized empty Git repository in /tmp/t/b/
Initialized empty Git repository in /tmp/t/a/.git/
warning: You appear to have cloned an empty repository.
[master (root-commit) 020a1fb] foo

To /tmp/t/b
 * [new branch]      master -> master

What are we doing differently?
