From 1e2e810f3f7cb6a163a0229ac37037e8c6744d72 Mon Sep 17 00:00:00 2001 From: Dominic Schlegel Date: Thu, 8 Mar 2018 12:13:38 +0100 Subject: Make salt minion module work on FreeBSD. Previously the module was not working under FreeBSD due to a different package name and some different paths. The module now has OS specific default values which can even be customized via corresponding cloud config variables.
