Hi,

There are many projects here and there (Termux, AnLinux, etc.) that are based on
some sorts of kernel-free images of a minimal Debian system to be used through chroot (other Linux) or PRoot (Android) or whatever environments.
Most of the time, it is provided as an archive file downloaded at their own upstream project through their own (G)UI interface for which the content can be more or less similar to what could be an «official» Debian one.

Is there something already available at Debian?
Something interesting to develop?

Thanks,
Patrice

Maybe I misunderstood, but you sound like you are after
something like:

sudo debootstrap \
/srv/chroot/debian-stable \
stable \
http://deb.debian.org./debian

Something interesting to develop?

Unsure, there are many alternatives to debootstrap already:
mmdebstrap, cdebootstrap, bdebstrap, to name the few I see with
a loose research with apt.

Have a nice day, :)

Some examples of those linked from this page:

Most Debian users are currently expected to create their own installs,
using either the official Debian installer or the tools it is based on
like debootstrap. One of the reasons for this is that packages often do system-specific configuration in their maintainer scripts (like the
systemd machine identifier or OpenSSH creating private keys), so you
can't always expect an install to be able to be duplicated safely.
There are folks working on reproducible installs though.

https://wiki.debian.org/ReproducibleInstalls

There have been five types of pre-installed systems available from the
Debian community; live images, cloud images, RPi images, minimal docker containers, and the WSL install. The first three of those are partition
images, but the WSL installer is basically a kernel-free rootfs tarball
wrapped in a PE executable and the docker containers are similarish.
All of these have to work around the issue mentioned above.

https://www.debian.org/CD/live/
https://cloud.debian.org/images/cloud/
https://raspi.debian.net/
https://docker.debian.net/ https://wiki.debian.org/InstallingDebianOn/Microsoft/Windows/SubsystemForLinux

There are lots of potential artefacts Debian could create from our
binaries rather than expecting all users to install their systems.

There are lots of different types of installs being explored outside of
Debian, including system snapshots, server containers, app containers, appliance images, chroots/VMs under other operating systems etc.

Debian could potentially be converting our binary packages to each of
these different types of installs.

Debian users could then be directed by default to the most appropriate
install type for their use-case.

PS: a list of system/package build tools is here:

https://wiki.debian.org/SystemBuildTools
