Been looking at Aegir on ubuntu 11 server, it seems like it makes drupal management easier, it this true or just another overhead?

Is Aegir usefull or not for multi site and multiple site server?

Has anyone installed drush and Aegir into Fedora 14? What are the gotchas to watch out for? Is it safe enough to change the aegir.sh installation file to point to Fedora paths?

Thanks Roger
