Hmm, I was naively looking at the launch() code in src/activate/activate.c but seems my grepping skills lack the fu required :) So I guess it's exec_spawn() which sets up the final env which combines a calling env + stuff from the unit (Environment= etc) + pam + files. I can't quite grok which ones are there by default... I guess maybe just the PATH and local stuff as you suggest? Any further input on this or should I respin with this info?
