Этот двоичный файл занимает гораздо больше места, чем его динамический аналог, расположенный в e2fsprogs, хотя

Это из Synaptic.

statically-linked version of the ext2/ext3/ext4 filesystem checker
  
This may be of some help to you if your filesystem gets corrupted enough
to break the shared libraries used by the dynamically linked checker.

This binary takes much more space than its dynamic counterpart located
in e2fsprogs, though.

You may want to install a statically-linked shell as well, to be able
to run this program if something like your C library gets corrupted.
