Archive extraction has optional support to extract all-zero chunks as
holes in a sparse file.
* filesystem specific attributes, like ext4 immutable bit, see :issue:`618`.
* For hardlinked symlinks, the hardlinking can not be archived (and thus,
the hardlinking will not be done at extraction time). The symlinks will
be archived and extracted as non-hardlinked symlinks, see :issue:`2379`.
Are there other known limitations?
