There is no real trick behind it, you just use debbootstrap. If you want
to create the chroot in the directory "sid-sparc-sbuild", you run:

$ debootstrap --no-check-gpg --arch=sparc64 --variant=buildd unstable \
  sid-sparc64-sbuild ftp://ftp.debian-ports.org/debian

However, this will currently fail for sparc64 as the libpcre3 package is
not installable from *unstable* as I had to built it manually with tests
disabled and therefore had to upload it to the *unreleased*

As a workaround, you need to run debbootstrap with "--foreign" which
will just download the packages, unpack them but not configure them:

$ debootstrap --no-check-gpg --foreign --arch=sparc64 --variant=buildd \
  unstable sid-sparc64-sbuild ftp://ftp.debian-ports.org/debian

Once this has finished, you change into the directory you just created:

$ cd sid-sparc64-sbuild

Then wget the libpcre3 package;

$ wget

Then chroot into the newly created build root:

$ chroot .

Install the libpcre3 package manually:

$ dpkg -i ibpcre3_8.35-7.1+sparc64_sparc64.deb

And finally run the second stage of debbootstrap:

$ debbootstrap/debboostrap --second-stage

After that, you need to add entries to the etc/apt/sources.list (best
done from outside the chroot):

deb http://ftp.debian-ports.org/debian/ unstable main
deb http://ftp.debian-ports.org/debian unreleased main
deb http://incoming.debian-ports.org/buildd unstable main
deb-src http://ftp.debian.org/debian/ unstable main
deb-src http://incoming.debian.org/debian-buildd buildd-unstable main

And add the Debian Ports GPG key (this has to be done inside the

$ gpg --keyserver pgp.mit.edu --recv-keys A53AB45AC448326E && gpg
--export --armor A53AB45AC448326E |apt-key add -

Then the chroot is basically set up. But you need to add a configuration
for sbuild, namely:

root@ravirin:~# cat /etc/schroot/chroot.d/sid-sparc64-sbuild
description=Debian sid chroot for sparc64

That should be all. On a new machine, you also need to run
"sbuild-update --keygen" after creating .gnupg in the home
directory of the root user (mkdir /root/.gnupg).
