New comment by sgn on void-packages repository https://github.com/void-linux/void-packages/issues/40858#issuecomment-1332306349 Comment: Switch `gpsd` to run with group `dialout` instead of `gpsd` would work, but I don't think it's a correct thing to do. I **think** you should either `chown gpsd /dev/ttyACM0` or `chgrp gpsd /dev/ttyACM0` before running gpsd. I don't really know about `gpsd`, just a pure guess.
