Re: Waydroid on openSUSE and binder

["Sebastian Hörberg" <sebastian@cozycabin.se>]

Hi again, Jim!

Got distracted by some other things, but I have a partial success to this!

Managed to build a custom kernel and after some messing with waydroid it 
seems to work just fine. You can find my work repo here: 
https://build.opensuse.org/package/show/home:shorberg:branches:Kernel:stable/kernel-source

Steps necessary to try out (coming from your packages):
1. Remove anbox-modules-dkms
2. install kernel-default from linked repo
3. boot to new kernel
4. run reinit waydroid `waydroid init -f <etc>`
5. for me it mounted /dev/binderfs with wrong permissions, fixed by 
`chmod 777 /dev/binderfs`


I'll continue to test it in the coming days to make sure all is working 
as it should.


Best regards,
Sebastian
