Support installation on OpenBSD/amd64

[leonstafford]

Unable to install on OpenBSD

Add support for installation on OpenBSD, doas v sudo, ksh over bash

Haven't looked into what is required for PR yet

[wjdp]

I have zero experience with BSD, would appreciate some help here.

[leonstafford]

@wjdp happy to help! Wanted to get the feature request in at least. I have zero experience with Go, but should be able to do some prep/maybe a PR.

Thinking out loud:

• see what errors occur when the platform check is removed
• check for sudo calls, see how other projects have added doas support
• check for bash usage, see if it can change to sh or detect/switch if no bash, but have ksh
• see if there's a way to add OpenBSD tests to current CI

[leonstafford]

Checking out source allows it to build and execute fine for me on -current version of OpenBSD.

So, will check what can be done to the docs / public install script currently failing

[leonstafford]

public install script generated by https://github.com/goreleaser/godownloader, no longer actively maintained, but has some activity in repo.

If contributing upstream to godownloader doesn't make sense, can look to patch current generated installer script to support OpenBSD

Caddy installer script for reference supporting OpenBSD

[leonstafford]

alternatively, add notes in docs for installation on OpenBSD:

• build from source (just go dependency)
• alternative copy pasta install command using ftp
• go get possible?

[leonstafford]

may also be able to adjust goreleaser usage to build release for OpenBSD, similar to recommended install steps for Windows

Have merged the MR but not on a machine where I can tag a new release today. Should be able to soon.

Hi @leonstafford. Release is done, can you pull one of the binaries and check it works on your machine?

@wjdp many thanks! Working well here (amd64) 😸
