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.
