  56 # In February 2023 we stopped to create and update GIO module cache for 32-bit
  57 # modules at /usr/lib/gio/modules/giomodule.cache so this file is never created
  58 # on new installations.  However, if we are updating from an older installation
  59 # the file could be there occupying space and possibly create confusion.
  60 #
  61 # So let's cleanup that.
  62 #
  63 # The following two lines should be removed only after there are no modules
  64 # delivered to /usr/lib/gio/modules/ and some reasonable time passed so
  65 # everybody already updated their installations and there is no
  66 # /usr/lib/gio/modules lingering around.
