Agent doesn't replace variables in environment variables

[soenkeliebau]

The agent replaces three paths in config files that are downloaded from config maps:

• configroot
• logroot
• packageroot

These replacements should also happen in environment variables that are added to pods (see below for an example), but this is not currently working.
