# If we are using NetworkManager then we have to avoid having the kernel
# configure ipv6 addresses on an interface (via router advertisements)
# until NetworkManager starts. If the interface is configured by the
# kernel before NetworkManager then NetworkManager will ignore the
# interface and not configure ipv4 on it. It does this because it assumes
# some other entity is in control of the interface.
# Debian has a many year old long bug report detailing this behavior with
# the most interesting comment being at the end:
