# Clean up old AppArmor profile for upgrades from Ubuntu 10.10 to 11.04
# and 10.04 to 12.04 (ie, dhcp3-client -> isc-dhcp-client transition).
# This is needed (as opposed to simply waiting for a 'purge') because
# the dhclient3 and dhclient profiles provide AppArmor rules for the
# same binaries (/usr/lib/NetworkManager/nm-dhcp-client.action and
# /usr/lib/connman/scripts/dhclient-script) and not moving the old
# profile aside would mean that the old rules for these binaries take
# precedence over the rules provided by the new dhclient profile, since
# the old one is loaded after the first. (LP: #688191)
