Keep group permissions?
See original GitHub issueHow difficult would it be to replace setuidgid with something else that would preserve group permissions? The removal of additional groups can cause headaches when dealing with some hardware.
For example, on Jetsons the GPU is assigned to the nvidia group. Or audio devices like USB microphones belong to the audio group. Rather than needing to create custom udev rules to work around these restrictions, and possibly open up security holes by allowing global r/w to devices that shouldn’t necessarily be that accessible, it would be nice if the nodes could be launched with the group permissions intact.
