Cannot pass data from signup form to installation profile

Hello everybody,

I have recently installed Aegir (6.x-2.1) on a Debian 6.0.10 (squeeze) following the instructions found here http://community.aegirproject.org/node/400.

I have followed the instructions found here: https://mig5.net/content/developing-aegir-extending-aegir-and-communicat... and here: https://groups.drupal.org/node/97039, to pass data from signup form to platform's installation profile, but with no luck.

in more details I created a drush script hosting_school.drush.inc in my hosting_school module and inside the script i have implemented hook pre_hosting_task, drush_hosting_school_pre_hosting_task . Then I created drush script school_name.drush.inc in .drush folder and I have implemented hook pre_provision_install, drush_school_name_pre_provision_install.

The problem is that while method drush_hosting_school_pre_hosting_task is properly invoked, method drush_school_name_pre_provision_install is not.

Am i missing something from the instructions?
