-Subject: [PATCH] inherit systemd environment when calling generators.
-
-Systemd generators need access to the environment configured in
-stage-2-init.sh since it schedules fsck and mkfs executions based on
-being able to find an appropriate binary for the target filesystem.
-
-With this commit I am altering the systemd behaviour since upstream
-tries to gather environments with that they call
-"environment-generators" and then seems to pass that on to all the other
-executables that are being called from managers.
