I'm actually not in group video. I have simply been granted access to the /dev/video* devices by virtue of having logged in at the console. That explains why Debian doesn't have this—Debian is not trying to use ACLs for device access. I hadn't needed it for the video devices because of this in 70-uaccess.rules:

# Webcams, frame grabber, TV cards
SUBSYSTEM=="video4linux", TAG+="uaccess"
SUBSYSTEM=="dvb", TAG+="uaccess"

I've corrected that (and added myself to several other groups I can see I probably want to be in based on my "other" user on the system as well.

I think the TAG+="uaccess" for SUBSYSTEM=="media" is a good idea, since I think the uaccess tag for console users is probably intended by RedHat's holy Gnoman Empire, if one is not using udev/systemd, ACLs won't get assigned and the group is necessary. I'll leave the question of closing this or considering implementing it to you and the systemd team.


As said, this is not something that should imho be addressed via downstream patch. So if you have an interest in this, please consider filing this upstream.

Let me add here:
You clearly have shown an interest, otherwise you wouldn't have filed a bug report in the first place. The reason why I ask you to forward / file this issue directly upstream is, that I don't have such a hardware. It's possible, that upstream has follow-up questions which I won't be able without being able to reproduce the issue.

Michael
