Issue #13679 has been updated by Daniel Friesen.

I do have a suggestion on how to best handle compatibility.

Take a bit from single quote style escaping:
dbpassword = asdf$asdf # $asdf is considered a variable
dbpassword = asdf\$asdfasdf # \ is an escape this turns into 'asdf$asdfasdf'
dbpassword = asdf\\$asdf # The \\ self escapes to a single \ and $asdf is 
considered a variable
dbpassword = asdf\asdf # The \ has nothing to escape so it's considered a 
literal part of the data and kept

This would avoid any issue with existing configuration using a \ except for the 
one case where someone uses a \\.

Or there's always sql quote escaping style ('') / %time format escaping (%%):
dbpassword = asdf$$asdfasdf

Treating $$ as literal there.

Bug #13679: dollar signs can't be used in puppet.conf
https://projects.puppetlabs.com/issues/13679#change-60378

Author: Daniel Friesen
Status: Code Insufficient
Priority: Normal
Assignee: 
Category: settings
Target version: 
Affected Puppet version: 
Keywords: 
Branch: https://github.com/puppetlabs/puppet/pull/640


Plain dollar signs ($) can't be used inside puppet.conf.
I tried quoting text with quotes and escaping with \ and neither work.

This is important in the case of passwords. If you have a long mysql password 
for stored configs like "sdf^3wre$4aer..." you get an error saying that $4 is 
not defined.
