1. remove the _normal suffix, as it is not used 2. add a selector to look for the variable $lsbdistcodename being set and use that in selecting a template this is useful to create a Debian_Etch.erb and a Debian_Lenny.erb which can have different values. For example the Debian Etch version of openssh does not have the AllowAgentForwarding option, and if it is included, ssh will fail to start

|
#
|
|

|
|
# set this for example to "foobar root"
|
