Drupal alpha

This isn't pretty. And i've probably left out a critical step.

Core concepts: making some changes directly in the database. Enabling head2head and alpha2alpha in the database (setting both status and schema_version). Manually commenting out the update hooks that i did in the database to make user module's updates work so that alpha2alpha's can work.

Setting the line in alpha2alpha.module to give the current version:

<?php
  $version = variable_get('alpha2alpha_version', 7);
?>

Alpha to alpha upgrades are officially unsupported and the HEAD2HEAD module focuses on precisely that, continuous changes in CVS HEAD not upgrades between the alphas.

UPDATE: Head2Head does have an alpha2alpha module, use that. Consider the below a learning exercise... in examining existing modules that may solve your problems carefully!
