commit 43dd92024ab54921fbf85285d04344cb2c6e77cc
Author: Ludovic Courtès <address@hidden>

    union: Don't traverse sub-directories only found in one element of the 
union.
    
    This significantly reduces I/O when building profiles, especially with
    lots of package-specific sub-directories (such as 'share/emacs/24.3',
    'texmf', etc.)
    
    * guix/build/union.scm (union-build)[file-tree](others-have-it?): New
      procedure.  Use it in the 'enter?' parameter of 'file-system-fold';
      change 'skip' parameter accordingly.
    * tests/union.scm ("union-build"): Ensure that 'include' is a symlink
      and 'bin' is a directory.
