[chef] Dynamic template path.

[< >]

I need to create a template for network scripts, eg:

template "/etc/sysconfig/network-scripts/ifcfg-xxx" do
.
end

Where "xxx" is specified in either default or override attributes. I have
tried:

template "/etc/sysconfig/network-scripts/ifcfg-xxxi#{node['xxx']}" do
template "/etc/sysconfig/network-scripts/ifcfg-" + node['xxx'] do

path = "/etc/sysconfig/network-scripts/ifcfg-" + node['xxx']
template path do

but all give knife upload errors of the form:
FATAL:
/hepuser/crlb/Git/chef-repo/cookbooks/nimbus/recipes/KVM_VMM_control_node.rb:46:
syntax error, unexpected tIDENTIFIER, expecting ']'

Suggestions please.
