# lo is brought up earlier, which will cause the upcoming "ifup -a" to fail

# with exit code 1, due to an "ip: RTNETLINK answers: File exists" error during

# its "ip addr add ..." command, subsequently causing this unit to fail even

# though it is a benign error. Flushing the lo address with the command below

# before ifup prevents this failure.
