Moving to a new server still assumes old directory structure

After moving Civi to a new server it still assumes the old directory structure.

What I did:

• copy the directory structure
• import the database
• adapt settings in settings.php and civicrm.settings.php
• Update Directory Path and URL at http://<drupal_site>?q=civicrm/admin/setting/updateConfigBackend&reset=1
• i provide the new directory path (/home/www/htdocs/testcontact/sites/default/files/) and the base URL (http://testcontact/)

That's where I get the error

We could not write /var/www/foee_contact/sites/default/files/civicrm/templates_c/en_US/ConfigAndLog/Config.IDS.ini. Have you moved your site directory or server?

Please fix the setting by running the update config script

Note that /var/www/ is where my old server had it's document root. The new server has it's document root in /home/www/htdocs. This is not taken into account by CiviCRM.

My assumption is that Civi takes the old path from the database table civi_domain.

Workaround:
I created a symbolic link on the new server simulating the old structure (inspired by the hint given at http://wiki.civicrm.org/confluence/display/CRMDOC/Moving+an+Existing+Installation+to+a+New+Server+or+Location)
