etmpfiles and udev cannot set permissions in /dev/: "Invalid Argument".
Since more than a month now, when
system/etmpfiles starts up the etmpfiles-dev service, it fails at setting permissions of files in /dev/.
A manual run of /etc/init.d/etmpfiles-dev (as root) prints the following to the terminal:
* Setting up tmpfiles.d entries for /dev ...
fchmod() of /dev/fuse failed: Invalid argument
fchmod() of /dev/uinput failed: Invalid argument
fchmod() of /dev/snd/timer failed: Invalid argument
fchmod() of /dev/snd/seq failed: Invalid argument

fchmod() of /dev/vhost-net failed: Invalid argument
fchmod() of /dev/vhost-vsock failed: Invalid argument [ !! ]
* ERROR: etmpfiles-dev failed to start
[/tt]
Another way to try to set permissions of files under [tt]/dev/[/tt] is udev. I have an udev rule that wants to set the permissions of [tt]/dev/fuse[/tt] to [tt]0666[/tt]:
[code]
KERNEL=="fuse", GROUP="fuse", MODE="0666"
When I load the fuse kernel module, I observe that in the result /dev/fuse has the correct group ownership but wrong permissions (0600: Readable and writable only by the owner).
Running udevd with debug options prints the following to the terminal when loading the fuse kernel module:

Note the fuse: Failed to set owner/mode of /dev/fuse to uid=0, gid=500, mode=0666: Invalid argument.
I stumbled upon this since I failed to get /dev/kvm to be group read and writeable, what I want to achieve for QEMU.
System information:
What can be the issue here?, what might block etmpfiles or udev to set the permissions?
A manual chmod 0666 /dev/fuse works without issues.
Regards!
