Oh sorry, meant to open this against my own branch. Closing for now.

Fyi there was a work in progress to add testing for another OS via vmactions, which also has Illumos. That would probably be preferable to adding another CI provider #3965

[tgross35]

I stand corrected, they don't have Illumos. Does Cirrus? As I understand it, they have everything that is available via GCP.

edit: er wait, is omnios illumos? If so then vmactions does have it https://github.com/vmactions/omnios-vm

[sunshowers]

Thanks, I'll look at that. OmniOS might work!

[tgross35]

You know, we could use a target maintainer for Illumos (or at least a platform support page). It seems like you have been working with the platform a lot, any chance you would be willing to sign up for that? It's the zero commitment, just means that we have somebody specific to ping in the rare cases there are platform-specific questions.

If yes, just submit a rust-lang/rust PR. Copy TEMPLATE in https://github.com/rust-lang/rust/tree/master/src/doc/rustc/src/platform-support to illumos.md, update it (doesn't have to be very detailed), then update the table.

Solaris could use a platform page as well in case there is overlap there.

Cc @jclulow @pfmooney in case you might also be okay with being listed for illumos and/or solaris.

We'll want to be careful using OmniOS, as they ship some extensions that are not in the base illumos bits.

Patrick and I have been acting in this capacity for years, but were only recently informed about the maintainer page stuff. There's a PR open right now to add a page: rust-lang/rust#132477

We've been separate OSes for 14 years, so there's not a great deal of overlap per se. I suspect folks from the Solaris team at Oracle would be best placed to handle their own page.

It looks like OmniOS was added by request vmactions/solaris-vm#34 maybe worth asking for vanilla Illumos for the ecosystem as a whole (even if we wind up not using it here).

Timing :) glad to hear it is in the works, thanks for the link! I think we really only started trying to fill out those pages in the past few months, most didn't exist until the past year.

👍 I just know the changes often come together to this repo but didn't know the background, thanks for the background.

I have a mostly working OmniOS-based build at sunshowers#3 -- will send a PR once the upstream prereqs are met.

[sunshowers]

We've had a closely look, and unfortunately OmniOS is different enough from upstream illumos that we don't feel confident. (For example, OmniOS has an inotify implementation that upstream doesn't, and it would be pretty easy to accidentally introduce inotify-related symbols to the illumos build.)

We'd like to not just throw illumos CI over the wall, and instead would prefer to fully support it and address issues in a timely manner. Buildomat is the system we use for our own CI at Oxide, so using that aligns with us.

Based on this, we believe that Buildomat is the way to go. What do you think?
