I built Chromium/ozone/wayland,

args.gn like so:

use_ozone = true
use_goma = true
symbol_level = 2
is_component_build = true
dcheck_always_on = true

on weston nouveau. (There is no nouveau appropriate use_XXX_minigbm= setting? Certainly it's worth updating the docs for what to do with nouveau.)

crashed like this on weston:
