Ah shoot. When we moved to .xz checks were made to ensure it was supported everywhere. we missed this.

Can it be enabled through an external plugin or will we need to revert to .tar.gz for BSD usages?

[sdassow]

We could use gtar (GNU tar) instead, which can be installed from packages/ports.

First off, this is on OpenBSD only, the others I checked (NetBSD, FreeBSD, DragonflyBSD) support it.

Other than that, using gtar wouldn't be the best user experience since it means installing something else first.

Unusual for someone to reply to their own suggestion going against it ;).

It sounds like we have no choice - should we just create .gz when run on OpenBSD? I'm not sure it matters too much. It may also mean we have to use that when packaging /for/ openBSD as well, or you won't be able to open the archives.

Just thinking out loud ;).

I'll have a look and brew something up. When I found this I just created an issue for later.

For distribution it doesn't matter as much. For source distribution not at all since that's usually handled in the ports tree for proper OpenBSD packaging as a build dependency. For binary distribution it means a small inconvenience having to manually install GNU tar and/or xz first.

Sorry I missed this before commenting on the PR. Typically we want to put the package install / additional dependency on the developer not the end user. Is it a bad thing to adapt the fix so it avoids that compression for both developer and user?

Solved in the PR by using the target OS to switch format for OpenBSD.
