#
# Title: pbuilder-runhooks
# Description User hooks for pbuilder package
# Programmed by: Dale Amon <amon@vnl.com>
# $HOOKDIR is set in /etc/pbuilderrc and contains a list of executable
# programs or scripts. The type is only limited by what you expect will
# be available in your chrooted environment after debootstrap has done
# an initial install. The functions must be named in the format:
# <prefex><digit><digit><descriptive name>. Currently only X is defined;
# scripts prefixed with X will be run just before the chroot environment
# is exited and the base.tgz file is created or updated.
# $BUILDPLACE is as used in pbuilder. When already inside chroot, this
# routine can be called with $BUILDPLACE='' (from pdebuild-internal)
# TODO: * Are there any other executable backup types we should
# filtered besides *~ and *.bak?
#
