I know there's a command to run a particular CI runner, but a) I don't know the syntax, b) not sure if I have permissions to do it?

[workingjubilee]

Let's make sure you can do that:

@bors2 delegate=try

@alex Generally you edit your PR desc so it has

try-job: job

And then @ bors2 try

See

rust/src/ci/citool/src/main.rs

I think this needs to follow the process for promoting to tier 2 with host tools - https://doc.rust-lang.org/beta/rustc/target-tier-policy.html#tier-2-with-host-tools, are you preparing that elsewhere? Config here seems OK, though it should probably be removing the tier 2 build from the dist-various builder?

Sure, I'm happy to fill out an MCP for this -- is there by chance a previous one you know of that I can use as a reference on the format/level of detail that's expected?

You'd want to find the previous (if one exists) proposal for this target and copy/paste the target policy, filling out any item with details since the last uplift (to tier 2, if that one exists).

rust-lang/compiler-team#864 is a tier 2 uplift but is broadly the right shape.
