I am following a tutorial about how to use chroot and set up a jailed dir. The process is to copy bash and the libraries it depends on into the 'jail' dir. To find the libraries bash depends on I use the comand:

ldd /usr/bin/bash
#which outputs
linux-vdso.so.1 (0x00007ffd4cb6f000)
libtinfo.so.6 => /lib/x86_64-linux-gnu/libtinfo.so.6 (0x00007f11c0bb5000)
libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f11c098d000)
/lib64/ld-linux-x86-64.so.2 (0x00007f11c0d5a000)

But whatever the first line of this output is, it is not required to be copied into the jail dir but all the files referenced on the other lines are. I would like to know why? And what is it?
