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

Currently (2013-04-04) I am using the following setup:

~/.pbuilderrc contains:

  NAME="$DIST-$ARCH"
  APTCACHEHARDLINK=yes
  DISTRIBUTION="$DIST"
  DEBOOTSTRAPOPTS=("--arch" "$ARCH" "${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-cran/"
  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 wheezey pbuilder images, the backports repository is not necessary.

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