I prefer user-specified locations to take precedence over system and other
default locations, and so I've changed way that the central-registry is
constructed on my systems. I've attached the patch that I apply to SBCL.
With this change, the current or default directory is highest precedence,
followed by ~/.sbcl/systems/ and then SBCL_HOME/site-systems .
My system also places /usr/share/common-lisp/systems at the end of all of
Is this something worth including in the default SBCL dist?
