When we had initscripts it was hard to do. Now, with systemd it's very easy to start notebook at system start and close it cleanly. I don't have service file which would work for package, I have one that works for development environment (I have sage:users who compiles different versions and I switch symlinks around, that's why I have notebook started that way). Anyway, this already contains clean way to shut down notebook (KillSignal and SendSIGKILL, it sends single ctrl-c for closing) and works remarkably compared to any initscript solution I've seen. That one might be used as starting point.

[Unit]
Description=Sage: Open Source Mathematics Software

[Service]
ExecStart=/usr/local/bin/sage -notebook
Restart=on-failure
User=sage
Group=users
KillSignal=SIGINT
SendSIGKILL=no

[Install]
WantedBy=multi-user.target

I have created my own sage notebook service like this

1) create directory /srv/sage and set owner to sagemath:sagemath
2) change the $HOME of sagemath user to /srv/sage (I think /srv/sage is more suitable for putting the service files than the default $HOME /opt/sage)
3) create systemd service

[Unit]
Description=A free open-source mathematics software system

[Service]
User=sagemath
Group=sagemath
ExecStart=/bin/sh -c 'cd $HOME && /opt/sage/sage -n interface="localhost" automatic_login=False'
ExecStop=/bin/kill $MAINPID

[Install]
WantedBy=multi-user.target

Since my sage notebook can be accessed from Internet (through lighttpd proxy), the automatic login is disabled. While for a default installation, this may not suitable.

I am going to include a systemd --user session unit when the next version is released that will be sage@$USER.service, so you can start it with whichever user you want. The next time i rebuild, so probably next month when 5.7 is due.

you can change it from that

Now that user sessions are actually working, could you try testing with a user unit instead of a system wide one?
