Bug#723977: missing symlink in /usr/share/common-lisp/systems

[Faré]

Diogo is correct that symlinks are (1) not needed anymore (2) frowned upon.

Indeed, unless you export XDG_DATA_DIRS or some weird shit like that,
then

(asdf::default-source-registry)

will end with

(:TREE #P"/usr/share/common-lisp/source/")

So that it should find systems under there even without any symlink to systems/

And indeed when I

HOME=/tmp sbcl --noinform --non-interactive --eval '(require :asdf)'
--eval '(format t "~A~%" (asdf:system-source-directory :cl-ppcre))'
/usr/share/common-lisp/source/cl-ppcre/

(The HOME=/tmp is so it won't use my personal configuration files)

I blame your misconfiguration.

If you don't use XDG_DATA_DIRS, do you have something in your configuration
that uses :ignore-inherited-configuration
then goes on to register /usr/share/common-lisp/systems ?

There is no such thing as a "necessary evil". If it's necessary, then
it cannot be evil, neither can it be good: it's a datum.        — Faré
