[ruby-core:120813] [Ruby master Bug#21095] Prefer `uname -n` over `hostname` in tests.

["Eregon (Benoit Daloze) via ruby-core" <ruby-core@ml.ruby-lang.org>]

Issue #21095 has been updated by Eregon (Benoit Daloze).


My 2 cents on this is it would be far less effort to add a test dependency on inettools in Arch than changing the specs and backporting.
IMO this is no bug, the issue only arises because Arch is trying to remove some common binary, such breakage is to be expected and seems easily fixable there.

----------------------------------------
Bug #21095: Prefer `uname -n` over `hostname` in tests.
https://bugs.ruby-lang.org/issues/21095#change-111681

* Author: ioquatix (Samuel Williams)
* Status: Closed
* Backport: 3.1: UNKNOWN, 3.2: UNKNOWN, 3.3: REQUIRED, 3.4: REQUIRED
----------------------------------------
It turns out that `hostname`, while a defacto standard, is not actually a standard in any official sense. On Linux, it's distributed as part of the `inettools` package, and while generally available on other platforms (BSD, Windows, MacOS), it isn't actually part of any standard.

The `uname(1)` system call and `uname(2)` command ARE standardised by POSIX and the Open Group, and are included in most base systems without the need to install extra packages (e.g. `inettools` on Linux).

As such, I was requested by the Arch Linux Ruby maintainer, to prefer using `uname -n` as they would like to drop the dependency on `inettools`. See <https://gitlab.archlinux.org/archlinux/packaging/packages/inetutils/-/issues/2#note_211062> for more context.

I've been asked if this can be back ported to 3.3 and 3.4 and while it's not strictly a bug, it will reduce friction in the distribution channels, so I'd like to propose that we backport to 3.4 and if possible 3.3 too.
