Really? That's not documented in the language guide, at least. Will that be
new in 2.6.8? Because it doesn't work in either 0.25.5 or 2.6.7. (I assume
you mean to use single quotes for the inner pairs of quotes.)
If you assign to temporary variables:
$a = template('a.erb')
$b = template('b.erb')
... "${a}${b}"
you get the desired behaviour, but it is rather clumsy. There are already
too many situations on Puppet where you need temporary variables.
----------------------------------------
Feature #5158: File resources: Make source/content parameters and the
file/template functions consistent.
https://projects.puppetlabs.com/issues/5158
Author: Nigel Kersten
Status: Accepted
Priority: High
Assignee: Nigel Kersten

Target version: Statler
Affected Puppet version:
Keywords: usability
Branch:
We have four main ways we can specify file content in a file resource.
1. The source parameter
2. The content parameter
3. The file function
4. The template function
These behave inconsistently in the following ways.
The source parameter, file function and template function all can take an
array. For source/file, the first file that exists will be used. For the
template function, we concatenate the templates instead.
The file function takes fully qualified paths only.
The template function takes fully qualified paths, or dereferences relative
paths as follows. 'foo/bar.erb' -> modules/foo/templates/bar.erb
The latter problem is relatively easily solved, particularly if we implement
#4885
We are going to have to break backwards compatibility to solve the first
problem however.
My feeling is that more people make use of the multi-select logic in the source
parameter/file function than make use of the concatenation of the template
function.
