It has to be the function find-init-path, I think...?

So, the culprit is whatever sets init-file-user (that find-init-path
uses)...?

Let me see:
 If I do a plain su, then init-file-user is "sb"

 If I do "/bin/su - root" then init-file-user is ""

But there may not be an easy way to undo this behaviour by setting
init-file-user, because by its nature this variable is used before any
init files are loaded... hm.
