Okay, I know someone here is trying this... success or failure?

I used these instructions a few weeks ago and they worked. You will need to download miniroot58.fs (not miniroot57.fs).

True indeed, the article was written a week before the release of 5.8...

This also probably works on other cloud providers if they support a virtualization layer that OpenBSD will work with. I've heard of successes here too: https://vultr.com/

Just be sure you use miniroot58.fs -- OpenBSD 5.8 wasn't released when this was written.

What is the technical blocker to installing OpenBSD without a FreeBSD shim, e.g. is there incompatible code in the OpenBSD installer?

5.8 is still currently in development/snapshot - not for amateur users.

5.7 is the latest official release. 5.8 is due on Nov 1.

Tangentially related at best...anybody here succeed doing PXE with virtualbox's tftp and openbsd? I get an unhelpful error msg.

Vultr allows installing from ISO, so no need to shim. I can verify that OpenBSD 5.7-stable will run with no issues. One thing to watch out for is that outgoing TCP connections to port 25 are blocked until you ask them to open it up.

On digital ocean you get a very limited set of boot options. You can't provide them your own installer, boot image, kernel, iso, or any of that jazz.

You also don't get a pre-boot console.

For linux, they don't even let you provide your own kernel in userland or the like, so there's actually no way to install a BSD from a linux shim on DO.

FreeBSD on DO is the only way to get an instance that is capable of booting anything non-linux, so it's necessary to start from freebsd.

Edit: It looks like the kernel limitation has been lifted for some linux instances too. See: https://www.digitalocean.com/community/tutorials/how-to-upda...
