## Why is it called _flora1_?

Because _flora2_ is already in the works!

## Notes

### Starting with Linux systemd service

#### Issue

After updating from *Raspbian Buster* to Raspberry Pi OS *Debian Bookworm*, the service wouln't start. The reason was that some code in `lgpio` used for accessing GPIO pins tries to write into the working directory (see https://github.com/gpiozero/gpiozero/issues/1106), which was not permitted.

#### Workaround

* Split WorkingDirectory and RuntimeDirectory (see [09_software/template.service](https://github.com/matthias-bs/Flora1/blob/2-starting-via-linux-systemd-service-fails/09_software/template.service))

  * WorkingDirectory=/var/run/flora/

  * RuntimeDirectory=/opt/flora

* Create `/var/run/flora` at startup (if will not persist if created manually!)

  * See https://serverfault.com/questions/824393/var-run-directory-creation-even-though-service-is-disabled

  * In `/usr/lib/tmpfiles.d/var.conf`:


    add


    `d /var/run/flora 0770 root daemon -`
