# They are already removed in postinst, but if configuration fails,
# they will still be around. Removing the package without
# configuring would then allow the diversions to leak.
#
# So we catch them here. This cannot wait for postrm because that
# would break error recovery during upgrades: after the old, working
# version re-adds the diversion in preinst, the diversion would be removed
# again in postrm. More generally, removing a diversion requires
# a guarantee that the conflicting file is not present any more,
# and we cannot guarantee that if some other version of
# binutils-multiarch is installed.
