Enable native BinderFS support in linux-omarchy for Waydroid

[roubilibo]

Proposal

Enable native BinderFS support in the linux-omarchy kernel configuration.

Current situation

On Omarchy 4.0.4-1 with linux-omarchy 7.2.5-3, the kernel does not provide the Android Binder/BinderFS configuration needed by Waydroid:

CONFIG_ANDROID=y
CONFIG_ANDROID_BINDER_IPC=y
CONFIG_ANDROID_BINDERFS=y
CONFIG_ANDROID_BINDER_DEVICES=""

To run Waydroid, I currently need the out-of-tree binder_linux-dkms package. The module is loaded as:

/lib/modules/7.2.5-3-omarchy/updates/dkms/binder_linux.ko.zst

and the kernel reports that it is an out-of-tree module that taints the kernel.

Requested change

Please consider enabling BinderFS in the linux-omarchy kernel configuration using the options above, or documenting the intended supported approach for Waydroid users.

This would avoid requiring a DKMS module that has to be rebuilt after every kernel update and would follow the BinderFS configuration recommended by the ArchWiki Waydroid documentation:

https://wiki.archlinux.org/title/Waydroid#Using_binderfs

Test system

• Omarchy: 4.0.4-1
• Kernel: 7.2.5-3-omarchy
• CPU: AMD Ryzen 5 5600
• GPU: AMD Radeon RX 6600
• Desktop: Hyprland
• Waydroid: 1.6.3
• Waydroid image: GAPPS with libndk ARM translation

The current DKMS workaround allows Waydroid to start, but native BinderFS support would be cleaner and easier to maintain.
