This reduces the amount of shell in use, and the number of subprocesses
spawned by that, so our system environment generator is as fast as
possible when used in the critical startup path.
It adds a new system environment generator so that the system flatpak
installation can be used outside of a user session. In particular, this
allows enumeration of system-installed flatpaks in gnome-initial-setup
in order to set parental controls on them.

This is a script that program that gets run by systemd
before every user service to set up the environment.
See systemd.environment-generator(7) for details.
