perforate (1.2-6) unstable; urgency=medium

  Since trixie, the perforate package is obsolescent:
  + zum-like functionality is provided by cp --sparse and --reflink
    (this is the default for sparse files!)
  + finddup-like functionality is provided by hardlink -lc

  Please migrate away from perforate, it will be removed from forky.
