Please check [this merge request])(https://gitlab.common-lisp.net/asdf/asdf/-/merge_requests/147) and the corresponding ASDF issue.

Is CLISP bundling an up-to-date version of ASDF?

Please let me know, and if the above do not address the issue, open a new issue on the ASDF gitlab site and I will see about getting this fixed and issuing a bug fix release.

It would be very helpful if the clisp community could point me at a Docker image for Haiku + clisp so that I could put this configuration into test.

Indeed, it would be very helpful to have a CLISP docker image for linux kept updated for test purposes. The lack of an official release version hampers my testing substantially; so much so that I have dropped clisp from the test suite. It's impossible to know what to test when there hasn't been an official release in 14 years.

Haiku is an operation system different from Windows, Linux or *BSD. Still,
in many respects it can be considered Unix-like, which is especially true
when porting software to it.

CLISP was recently ported to Haiku. In the *features*, CLISP on Haiku
defines both :UNIX (i.e. Unix-like) and :HAIKU, and this is probably the
right decision. However, after (require "asdf"), *features* are changed,
:HAIKU is removed and :OS-UNIX is added. This is certainly something which
needs to be fixed. The desired solution would be to keep both :UNIX, :HAIKU
and to add :OS-HAIKU.

Here is the analysis from CLISP development list:
```
(defun detect-os ()
"Detects the current operating system. Only needs be run at
compile-time, except on ABCL where it might change between FASL compilation
and runtime."
(loop* :with o
:for (feature . detect) :in '((:os-unix . os-unix-p) (:os-macosx
. os-macosx-p) …
(:haiku . os-haiku-p))
:when (and (or (not o) (eq feature :os-macosx)) (funcall detect))
:do (setf o feature) (pushnew feature *features*)
:else :do (setf *features* (remove feature *features*))
:finally
(return (or o (error "Congratulations for trying ASDF on an
operating system~%~ that is neither Unix, nor Windows, nor Genera, nor even
old MacOS.~%Now you port it.")))))

That is somewhat brittle code that side-effects *FEATURES*. It contains a
special bypass to allow :OS-MACOSX to live there beside :OS-UNIX, but
there’s nothing equivalent for Haiku. Whether Haiku is considered a UNIX or
not I won’t debate.

I call such code /brittle/ because there’s an undocumented (non-explicitly
mentioned) dependency on element order in some innocuous list: If
:os-macosx were before :os-unix in the A-list, that code would not set –
and rather delete – :OS-UNIX in *features*.

I would have appreciated a tiny comment like

:for (feature . detect) :in '(…
(:os-unix . os-unix-p) (:os-macosx . os-macosx-p) ; Beware,
unix must come first!
