This is as much as anything an annoyance, but down the road it might actually break something.

When I go into single user mode and load the network (/etc/init.d/network start) so that I can access the network to fix the problem I get an error message that modprobe.conf is depreciated and I should be using modprobe.d   Everything still works, but someone might want to fix this before something down the road actually breaks this and then you can't get into network mode when in single user mode.
