Clarify: what ASDF is used by the lisp implementations?
The web page - https://cl-docker-images.common-lisp.dev/images/development.html - says:
Additionally, the following Lisp utilities are installed:
ASDF v3.3.4: The source code is located in /usr/local/share/common-lisp/source/asdf. The first time you attempt to use ASDF for anything non trivial, it will upgrade itself to this version.
Does it mean the lisp implementations are configured to use this ASDF installation instead of the default ASDF that comes with the lisp impl?
For example, when a user simply runs sbcl
or ccl
does he anyhow get this ASDF v3.3.4 installation, or the default ASDF normally coming with the lisp implementations will be upgraded to that version at some point?
I have tested, SBCL and CCL seem to use different ASDF version, but the wording of this paragraph leaves impression the ASDF version may be overridden for all the implementations.
