  I would have shared your concern if that was what I observed.  naturally,
  mapping everything to the root would be counterproductive, but at least
  under Allegro CL, the following mapping:

(logical-pathname-translations "TDN")
=> ((#l"**;*.*" #p"/home/tdn/"))

  does not map everything to the root.  I actually use several
  subdirectories under the TDN host, some of which have their own logical
  pathname host because it is useful to differentiate between absolute and
  relative pathnames, such as for an archive whose absolute mapping is to
  the root of the date-based archive directory hierarchy, and the relative
  mapping is to the current date within that archive.  e.g.,

(logical-pathname-translations "archive")
=> ((#l";*.*" #p"archive:1998;12;23;")
    (#l"**;*.*" #p"tdn:archive;")))

  this may look funny, but the point is that the first of these is actually
  recomputed every midnight, and does not want to do the mapping that the
  constant part does.

  I get the impression that you think there should have been a **;*.* at
  the end of the destinations, too.  I have always figured they would have
  to be there.  mapping everything to a single directory seems so utterly
  pointless that I can't see why it would be the expected behavior.
