# Workaround an issue when upgrading from anacron 2.3-33 (LP: #2006589)
# (this comment is copy-pasted across preinst and postinst scripts)
#
# anacron 2.3-33 has a bug where its postrm script unconditionaly removes the
# systemd service and timer files, thus disabling them; this issue only gets
# triggered upon package removal or upgrade since upgrades call the postrm
# script of the previous package version
#
# We work around this bug by backing up the corresponding files during our
# preinst and restoring them in our postinst.
