Persistent video 4 linux dev rules not preset

[ian-thompson-yv]

udev rules for v4l devices were removed from the Talos systemd-udev pkgs in https://github.com/siderolabs/pkgs/blob/f70250f91aa43c6972ccb121e6300ace9ffa535c/systemd-udevd/pkg.yaml#L33

The v4l-uvc extension does not put the rules back so video devices are not mounted in the way software expects. We have written our own local extension that is just the rules and we include this alongside the v4l extension.

Is it appropriate to raise a PR to add the new extension or should we raise a PR to modify the v4l extension and add the upstream rules (https://github.com/systemd/systemd/blob/9218e4eacc545a36a1275264013cb3d6b3eef41f/rules.d/60-persistent-v4l.rules#L4)

Yes, these seem useful and I guess it'd be easier to just keep them installed in the base system.

@smira does it seem fine to just install these rules in the base systemd package rather than via extensions? Those should do nothing without v4l2 modules

+1 for including it from systemd

I'm not sure, I feel it's easier to bundle it with v4l extension. It's a community extension. So @ian-thompson-yv if you want this, please send a PR with a change.
