If you want Home Assistant to be launched automatically, an extra step is needed to setup `systemd`. You need a service file to control Home Assistant with `systemd`. If you are using a Raspberry Pi with Raspbian then replace the `[your user]` with `pi` otherwise use your user you want to run Home Assistant. `ExecStart` contains the path to `hass` and this may vary. Check with `whereis hass` for the location.

sudo su looks always a bit wired. This will only work if the user is listed in the /etc/sudoers file which is no a lot of systems not the case. If this is Rapbian specific then we should mention that and keep the guide generic.

Sudo is Raspbian specific (I think)... but it caused me much consternation... So I would propose we have something to indicate that you may need to run as sudo if using raspbian.

In another PR (#873) we were talking about a Troubleshooting page for Rasbian. I think that this should be added there.

@bionutrient sudo is defiantly not specific to Raspbian or Linux for that part. It's a command that let's you execute a command with escalated privileges.

The su command when ran without specifying a user will default to the root user and is often called the superuser command(a bit misleading).

In this case your escalating privileges to root to run another command as root.
I think(haven't tested) that you could replace the command in question with

$ sudo cat <<EOF >> /etc/systemd/system/home-assistant@[your user].service

IF, you get an error message, and it fails to start Home Assistant, double check that your ExecStart=/usr/bin/hass points to the correct location...it's likely ExecStart=/usr/local/bin/hass If you didn't update it correctly, you may have to remove the home-assistant@pi.service file and then start over at the top of this instruction set using the correct directory.

Please follow the same style here and embed stuff like ExecStart= with `. It would also be possible to simple move and edit the file.

...it's likely ExecStart=/usr/local/bin/hass If you looks a bit misplaced.

To get Home Assistant's logging output, simple use `journalctl`.
