# The "postrm" of the "puppet-common" package in puppet 3.x contains a
# harmful "rm -rf /var/lib/puppet". which is called when that package
# is purged.
#
# This function rewrites /var/lib/dpkg/info/puppet-common.postrm to
# prevent data loss. See https://bugs.debian.org/825719 for more
# information.
