From a7e864e6e7de894d4edde4fff00e53dc6a0b5074 Mon Sep 17 00:00:00 2001 From: Matthew Heon Date: Fri, 31 Jul 2020 13:52:14 -0400 Subject: Ensure DefaultEnvVariables is used in Specgen When we rewrote Podman's pkg/spec, one of the things that was lost was our use of a set of default environment variables, that ensure all containers have at least $PATH and $TERM set. While we're in the process of re-adding it, change it from a variable to a function, so we can ensure the Join function does not overwrite it and corrupt the defaults.
