I have understood that difference, thank you. I am just assuming that
systemd may be configured in same manner.
The system I am building now is anyway pretty much oriented for one
user only. So not that I personally have need for user leverl
services, or for system I am preparing for others.
Those other services that are or shall be started by user, I am simply
starting in startup files, like application daemon, mcron
https://www.gnu.org/software/mcron/ -- or http server relating to user
space only, all this is 1-2 startup files, and they are not
supervised.

I am always using the latest, git clone -b master
git://git.sv.gnu.org/emacs.git from
http://savannah.gnu.org/projects/emacs/
It requires some environment variables, so using GNU Emacs as daemon
in userspace would require at least proper $HOME, $PATH, then $LC_ALL
on GNU/Linux system. And I am still not using the new version, I still
use the screen version.
It would require other variables for programming languages, like if
Perl is used within GNU Emacs, it requires $PERL5LIB or $PERL_UNICODE
and so on. So, placing user daemons into system supervision may not be
the best option, due to so many customization that have to be done for
the user, especially for GNU Emacs -- as one cannot know which
programming languages and their variables are required. If someone
programs in GNU Guile scheme implementation, that person may need
$GUILE_LOAD_PATH, and if it is not available in Emacs run by system
supervision, it becomes unusable.
