# Weird things you cannot do

Don’t name a capistrano namespace “rake”.  This breaks the db:migrate task, or any other built-in task that tries to run a rake command.  You’ll get a message like this:

executing "cd (your deployment directory) && #<Capistrano::Configuration::Namespaces::Namespace:0x107e01908> RAILS_ENV=production  db:migrate"

This error occurs with Capistrano 2.9, but does not occur with 2.5 - I’m not going to bother tracking down the exact version that introduced this issue.
