Immutable Fedora Silverblue can't join input group

[f0xb17]

sudo usermod -aG input $USER

This command will fail on Fedora {- add your immutable flavor here -} because it's an immutable system and Fedora uses two files to handle user groups.

sudo usermod -aG uinput $USER

This command will work fine. Don't know why, maybe because it's a non-internal user group? Maybe someone of you guys know more about it.

To fix that issue, that we can't join the input user group, we simply do that:

grep ^input: /usr/lib/group | sudo tee -a /etc/group
sudo gpasswd -a $USER input
newgrp input

Do a reboot and bam, Kanata Service will run fine on immutable Fedora.

I've tested that on Fedora Silverblue 42 Beta, but it should also work on Fedora Silverblue 41 and basically any other immutable flavor of Fedora.

I don't know if it's persistent, will test that when the final version is out, but as for my understanding /etc/ will get merged into the updated system image. Should work fine, therefore.

Maybe someone can test and confirm if that's the solution. For me, it worked ... finally. After hours of pain.
