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" 
    "${DEBOOTSTRAPOPTS[@]}")
  APTKEYRINGS="/home/jranke/.gnupg/pubring.gpg"
  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://ftp.de.debian.org/debian $DIST-backports main|deb http://localhost/r-cran $DIST-cran35/"
  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/buster-i386-base.tgz

With the pbuilderrc mentioned above, this can be created as a normal user with

  export ARCH=i386
  export DIST=buster
  sudo -E pbuilder create

When using these scripts on Debian, I used to configure sudo to allow my normal
user to use pbuilder, apt-get and the backporting scripts. Currently, I have 
set up my Debian installations using the Ubuntu like sudo configuration that
I select during the installation.

I am building other architectures on different machines (raspi: armxx) or in a
local chroot (amd64).
