And here's a rackup file for running a merb slice under unicorn. It
was helped a lot by the following blog post:

config.ru:
require 'rubygems'
require 'merb-core'
# Dir.chdir("/pathto/merb-slice")

:environment => ENV['RACK_ENV'] || "development",
:fork_for_class_load => false,
:init_file => File.dirname(__FILE__) / "config/init.rb")
Merb.environment = Merb::Config[:environment]
Merb.root = Merb::Config[:merb_root]
# Uncomment if your app is mounted at a suburi
#if prefix = ::Merb::Config[:path_prefix]
# use Merb::Rack::PathPrefix, prefix
#end
# comment this out if you are running merb behind a load balancer
# that serves static files
# use Merb::Rack::Static, Merb.dir_for(:public)
use Merb::Rack::Static, Merb.root+"/public"
require 'merb-slices'

$SLICE_MODULE = Merb::Slices.filename2module(slice_file)
require slice_file
end
Merb::BootLoader.after_app_loads do
# See Merb::Slices::ModuleMixin - $SLICE_MODULE is used as a flag
Merb::Router.prepare do

end
match('/').to(params)
else

end
end
end

exit
end

@slice ||= Merb::Slices.slices.first
end
end
Merb::BootLoader.run
