On my Raspberry Pi I installed Chia using the ARM deb package, and, In order to autostart services in Raspberry PI, I've to do this:

create the service:

$ cd /etc/systemd/system && sudo nano chia.service

Past the following code:

[Unit]
Description=Chia Services
Requires=network.target
After=network.target

[Service]
Type=forking
ExecStart=/lib/chia-blockchain/resources/app.asar.unpacked/daemon/chia start farmer
ExecStop=/lib/chia-blockchain/resources/app.asar.unpacked/daemon/chia stop
ExecReload=/lib/chia-blockchain/resources/app.asar.unpacked/daemon/chia reload farmer
User=pi 
 
[Install]
WantedBy=multi-user.target

Then, Must execute the mentioned systemctl commands.
