Personally I use a wrapper script that does the following (update the
chroot if it's older than 1 day), you probably want something in the
line. apt-get update etc are slow so you'll probably want to avoid
running it every time.



# pdebuild-normal script for my use.
BASENAME=base.cow

for BASETGZ in $(find /var/cache/pbuilder/ -maxdepth 1 -name ${BASENAME} -mtime +1 -print); do
    sudo cowbuilder --update --basepath ${BASETGZ}
    sudo touch ${BASETGZ}
done

mkdir ~/pending/$(date +%Y%m%d)/ || true
pdebuild --debbuildopts "-I -i -j5 " --buildresult ~/pending/$(date +%Y%m%d)/ --pbuilder cowbuilder -- --hookdir /home/dancer/bin/pbuilder-hook
