Today Alex Preisinger (giselher) announced that everything needed for a GHAMP (GNU/Hurd, Apache, MySQL, PHP) system has been packaged and is available in the main repositories. Additionally, PostgreSQL is available in testing (which depends on the new coreutils also in testing).
If you set up a server running Arch Hurd, we'd love for you to tell us either in IRC or on the mailing list :)
