This section discusses the characteristics and features you should be looking for to support a mod_perl-enabled Apache server. When you know what you want from your OS, you can go out and find it. Visit the web sites of the operating systems that interest you. You can gauge users' opinions by searching the relevant discussions in newsgroup and mailing-list archives. Deja (http://deja.com/) and eGroups (http://egroups.com/) are good examples. However, your best shot is probably to ask other mod_perl users.
