但是，这个二进制比位于e2fsprogs中的动态二进制占用更多的空间。

Question

这是Synaptic的。

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.

这是什么意思？

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

Answer 1

这意味着这个软件是静态的，所以它的所有组件都包含在单个deb包中。这种包不存在依赖关系。这是因为二进制文件是相联为静态 --它可能在一个文件中包含所有库。

您可以检查https://packages.ubuntu.com/focal/e2fsck-static上的包依赖项，以确认它没有任何必须安装的依赖项。
