This bot (and the win_chromium_gn_x64_rel using this config) also builds GN
non-component, and *could* run the apptests step, but it doesn't seem to run any
tests at all for now, so I've left it alone, sgty?

Sure, that's fine.

Is 'Win8 Aura' and 'win8_chromium_ng' the right bots to target?
(want to ensure they're not slated for imminent removal, etc.)

[Dirk Pranke, 2015/10/29 21:33:41]

Yes, this is the right bot to change.
