Triaging to Client component, jbudorick@ ,if there is a more specific place, please move.

I'm assuming you're talking about chromium.fyi:Fuchsia, chromium.fyi:Fuchsia (dbg), and tryserver.chromium.linux:fuchsia. If that's wrong, please let me know (and point me in the direction of the bot, because I see no other fuchsia bots listed in any of our master configurations).

typical configuration is:
 - trybot (release+DCHECKs)
 - waterfall release bot (release w/o DCHECKs)
 - waterfall debug bot

Fuchsia's bots' current configuration has the trybot running w/o dchecks. I'll send out a CL shortly that changes that to match the norm.

er, sorry, misread mb_config. fuchsia already matches the typical case. This would deviate.

Given that Fuchsia (dbg) exists, I think the only option here is switching the waterfall Fuchsia bot to have DCHECKs enabled, which is a deviation from how we typically configure waterfall bots. If that's what y'all want, though, that's fine with me.

Re #4: Is it only try-bots which have dcheck_always_on, then, and waterfall/Release bots don't?

I'm happy with this being covered by the Debug bot, in which case we should try to expedite getting that green (see  issue 743296 ).
