Waydroid can't launch: Can't open /dev/binder: No such file or dir

So I followed https://wiki.archlinux.org/title/Waydroid and installed `linux-zen` kernel.

Boot0005* Arch Linux Zen Secure Boot Bundled    HD(6,GPT,xxxxxxxxxxxxxxxxxxxxxxxxxxxxx)/File(\EFI\Linux\archlinux-linux-zen.efi)

Binder already inserted

$ sudo modprobe --first-time binder                     
modprobe: ERROR: could not insert 'binder': Module already in kernel

/dev/binderfs is present, however, /dev/binder is not

$ sudo ls -1 /dev/binderfs              
anbox-binder
anbox-hwbinder
anbox-vndbinder
binder-control
features

Also I removed binder_linux-dkms and anbox-modules-dkms-git.\

When launching waydroid this happens:

$ waydroid show-full-ui
[gbinder] ERROR: Can't open /dev/binder: No such file or directory
[15:36:58] Failed to add presence handler: None

I tried to link /dev/binderfs/anbox-binder to /dev/binder, after which waydroid doesn't give any errors but still doesn't launch.

$ sudo ln -s /dev/binderfs/anbox-binder /dev/binder
$ sudo chmod o=rw /dev/binder                                                     
$ waydroid show-full-ui                                                                                      
[15:44:06] Starting waydroid session
[15:44:06] Failed to start Clipboard manager service, check logs
[gbinder] Service manager /dev/binder has appeared

The same thing happens when binder_dkms-git is installed and /dev/binder is present.

So, what should I do to make it work?

I have the exact same problem. If I understand correctly when using the Zen kernel /w headers no DKMS modules are needed, so no binder_dkms is needed, right? I do not have it installed and boot into the Zen kernel and /dev/binder doesn't exist for me neither, even though the module is already in the kernel.

Is this issue related in your opinion? Can you conclude something useful from it?

After switching to the zen kernel, do

sudo waydroid init -f

Yeah that worked.
