Jeremy Stanley 0f8afeb8ad Silence drupal cron job
* modules/drupal/manifests/init.pp: Since the cron URL can return
content, write it to the bitbucket so that we don't annoy sysadmins
with cronspam every five minutes.

# == Class: drupal
#
# A wrapper class to support drupal project integration based on LAMP
# environment.
#
# Actions:
# - Prepare apache vhost and create mysql database (optional)
# - Install Drush tool with Drush-dsd extension
# - Fetch distribution tarball from remote repository
# - Deploy dist tarball and setup Drupal from scratch or
# upgrade an existing site.
#
# Site parameters:
# - site_name: name of the site (FQDN for example)
# - site_admin_password: password of drupal admin
# - site_docroot: root directory of drupal site
# - site_vhost_root: root directory of virtual hosts
# - site_create_database: if true, create a new database (default: false)
# - site_alias: drush site alias name
# - site_profile: installation profile to deploy
#
# Mysql connection:
# - mysql_user: mysql user of drupal site
# - mysql_password: password of site user
# - mysql_database: site database name
# - mysql_host: host of mysql server (default: localhost)
#
# Drupal configuration variables:
# - conf_cron_key: cron_key setting used for cron access
#
# Remarks:
# - the site lives in /srv/vhosts/{hostname}/slot0 or slot1 directory
# - the /srv/vhosts/{hostname}/w symlinks to slot0 or slot1 and
# points to actual site root. The upgrade process will begin in
# inactive slot so we can avoid typical WSOD issues with Drupal.
# - for temporary package/tarball download it is using the
# /srv/downloads directory.
