How to setup openrc:
--------------------
  # cgroup v1 or v2?
  ls /sys/fs/cgroup/
  # if unified (v2 only), Android needs v1 subsystems
  cat /proc/mounts | grep cgroup

  # for OpenRC (no systemd), add this to /etc/rc.conf or boot loader:
  rc_cgroup_mode="hybrid"

  Waydroid needs kernel 5.10+ with CONFIG_ANDROID_BINDER_IPC and CONFIG_ANDROID_BINDERFS enabled.
