   4 Subject: [PATCH] inherit systemd environment when calling generators.
   5
   6 Systemd generators need access to the environment configured in
   7 stage-2-init.sh since it schedules fsck and mkfs executions based on
   8 being able to find an appropriate binary for the target filesystem.
   9
  10 With this commit I am altering the systemd behaviour since upstream
  11 tries to gather environments with that they call
  12 "environment-generators" and then seems to pass that on to all the other
  13 executables that are being called from managers.
