      Here all the files from different TeX-related
      packages are collected in one directory. Of
      course, mktexlsr is called. Later placed
      directories take precedence. It is supposed that
      share and libexec are symlinked, and bin is
      recreated with wrappers for libexec-located
      linked binaries.
