New comment by SorrelArticulata on void-packages repository https://github.com/void-linux/void-packages/issues/40858#issuecomment-1332053131 Comment: It looks like gpsd is changing to user 'gpsd' and group 'gpsd'; instead of user 'gpsd' and group 'dialout' (group of provided special serial file). This does not match what the manpage says and is probably the cause of the issue here.
