This directory contains my scripts to build backports of R software from Debian
sid to older Debian distributions.

Currently I am using the following setup:

~/.pbuilderrc contains:

  NAME="$DIST-$ARCH"
  APTCACHEHARDLINK=yes
  DISTRIBUTION="$DIST"
  DEBOOTSTRAPOPTS=("--arch" "$ARCH" 
    "--keyring=/usr/share/keyrings/debian-archive-keyring.gpg"
    "${DEBOOTSTRAPOPTS[@]}")
  BASETGZ="`dirname $BASETGZ`/$NAME-base.tgz"
  BUILDRESULT="/var/cache/pbuilder/$NAME/result/"
  APTCACHE="/var/cache/pbuilder/$NAME/aptcache/"
  MIRRORSITE="http://ftp.de.debian.org/debian/"
  OTHERMIRROR="deb http://security.debian.org $DIST/updates main|deb http://localhost/r-cran $DIST-cran3/"
  COMPONENTS="main"

This means I have the appropriate aptcache and buildresult directories set up
under /var/cache/pbuilder. I have several pbuilder images used for package
creation under /var/cache/pbuilder, among others:

/var/cache/pbuilder/squeeze-i386-base.tgz

These have a standard Debian mirror, the security sources and the Debian
backports repository setup in their /etc/apt/sources.list, as well as my local
http package source where the r-base package build results are available. I
have also imported the apt key of my repository inside the pbuilder chroots.

In the wheezy pbuilder images, the backports repository is not necessary.

For some reason, the keyring option to debootstrap is not used (necessary on
Ubuntu) so I need to pass this on the commandline when building the pbuilder
chroot for wheezy-i386.

When using these scripts on Debian, I configure sudo to allow my normal user to
use pbuilder, apt-get and the backporting scripts
