Running debootstrap from source
You can run debootstrap from its source tree without installing it. This
can be useful if you want a quick way to make a Debian chroot on another
system, or if you are testing modifications to debootstrap.
First, get the source.
* Either by using git
git clone https://salsa.debian.org/installer-team/debootstrap.git
* Or by visiting <https://packages.debian.org/source/sid/debootstrap>
and downloading the tar.gz file
Then in the debootstrap source directory:
sudo ./debootstrap stable my-stable-dir
If you are running a multi-stage boot strap (for example for a QEMU
rootfs) you don't even need root:
fakeroot ./debootstrap --foreign --arch=armhf testing my-testing-dir http://deb.debian.org/debian
Of course you will need to execute the second stage as root to finish the bootstrap:
(on foreign hardware)
* Cross-strap support - so you can bootstrap a filesystem to the
point where it will successfully boot, and finish installing itself
without having to be running the target architecture or OS yourself.
This means you should be able to run
debootstrap --arch powerpc sarge ./sarge-ppc-chroot ...
on an i386 system, boot a powerpc box with sarge-ppc-chroot as its
root files system, and have it "work". The cross-hurd package does
something similar, and should be replaced by this feature.
* There should be some (better) way of telling debootstrap what "base"
packages you want to install -- this varies between making a chroot,
doing an install, and doing a buildd. Also, some installs want
different base packages (to setup networking, or kernels, eg)
If there's a problem with debootstrap that you need fixed, feel free to do
an NMU to fix it. Usual rules: try not to break anything, and mail the
patch to the BTS. Don't worry about asking first though.
However, note that debootstrap is now team maintained. Anyone in d-i can do
a release without the bother of a NMU.
