system installation - Install more packages with debootstrap

debootstrap is a tool which will install a Debian/Ubuntu base system into a subdirectory of another, already installed system.

The installation log ends like this:

. . . 
I: Validating xxd 2:8.1.0320-1ubuntu3

I: Validating xz-utils 5.2.4-1
I: Validating zlib1g 1:1.2.11.dfsg-1ubuntu2
I: Chosen extractor for .deb packages: dpkg-deb
I: Extracting base-files...

So it seems to me that the only package debootstrap extracts is base-files, right?

Is there any way for debootstrap to extract/install more packages?
Especially, I found that debootstrap doesn't even install linux kernel at all. Can I somehow let debootstrap to install linux kernel as well?

I haven't install kernel but have found this

In the link The code bit --include=iputils-ping is an example of how to add package but you after install the machine in a folder you like, you can chroot in that folder add all apt repo you like and give apt update && apt upgrade or apt install packXXX

To my study I have do this:
$ mkdir -p sviluppo/studio/progetti/docker/immagini/ubuntu19.10
$ cd sviluppo/studio/progetti/docker/immagini/ubuntu19.10
Importan do not forget to do a cd on the future chroot folder like mine above

$ sudo apt policy debootstrap

debootstrap: Installato: 1.0.116ubuntu1.1 Candidato:
1.0.116ubuntu1.1 Tabella versione: *** 1.0.116ubuntu1.1 500
500 http://archive.ubuntu.com/ubuntu eoan-updates/main amd64 Packages
500 http://archive.ubuntu.com/ubuntu eoan-updates/main i386 Packages
100 /var/lib/dpkg/status
1.0.116ubuntu1 500
500 http://archive.ubuntu.com/ubuntu eoan/main amd64 Packages
500 http://archive.ubuntu.com/ubuntu eoan/main i386 Packages

Then I have installed ubuntu 19.10 on my folder:
$ sudo debootstrap --verbose eoan ./
$ sudo vim ./etc/apt/sources.list
and change it to:

#deb http://archive.ubuntu.com/ubuntu eoan main
