Simple script that automatically creates and initializes a correct sf2 project for me.

sf2create.sh

#!/bin/sh

php composer.phar create-project symfony/framework-standard-edition $1

cd $1
ln -s web public

sed -i public/app_dev.php -e '/header/s|^|//|' -e '/exit/s|^|//|'

sudo setfacl -R -m u:www-data:rwX -m u:jthijssen:rwX app/cache app/logs
sudo setfacl -dR -m u:www-data:rwX -m u:jthijssen:rwX app/cache app/logs
