In Ubuntu, you just put a ?.service file in /usr/lib/systemd/system
There are probably already some examples there that you can use to see how
it's done. For example, when I run the tomcat 10 installation I get:
/usr/lib/systemd/system/tomcat10.service
which causes tomcat to start when I reboot.
Then you have to run
sudo systemctl daemon-reload
Eventually you will see a copy of the file in
/etc/systemd/system/multi-user.target.wants
and your service will now run after you reboot ( or simply run sudo
systemctl start <your_new_service_name>.service )
Isn't this how it works on other flavors of linux?

According to the web, and my experience, it doesn't work.
NP. I'll just make a systemd unit and do it right. There are 12
different kinds. Trying to read the docs and figure out what to do is
going to be fun. I just copy a template from the web that is suppose to do
what I want. There apparently aren't any tools to make this easier because,
"It's all really simple already." Conceptually, it does look fairly
straightforward, if I had the info I needed. Which is probably there. I
just have to do a lot of reading and get a lot of religion.
My executable runs and does what I want. Let's fire up the systemd
service and see what happens. Oh, SELinux happens.
I haven't played with SELinux. Perhaps now is a good time to learn. I am
somewhat curious why the SELinux interface tells me a temporary workaround
and not a permanent fix. But, with what it does tell me, I figure I have
to learn about SELinux policies.
Are you kidding me?
I have to install an _devel package. I can follow the cookie cutter
script, which has 10 nontrivial steps. I start, but I don't get the
results that the script tells me I should. Since I don't know what I'm
doing, I have no idea if this will be a problem or not.
There are only 10 or so man pages I need to read. I'm sure none of them
are short.
How long has this stuff been around now?
Am I missing something? Because it looks like something I stepped in once.
We went from adding a line in a file, to all this. It is allegedly more
secure.But it looks to me that things could be a lot easier and someone
made a big mistake somewhere.
I haven't decided how I'll proceed. I either turn off SELinux and start
my stuff automatically. Or keep starting it manually, as I do now. It's
on a box I like to keep secure, so there is that.
Is there a way out or around that I have missed?
