with --verbose, udf prints "no modprobe"

When I run udf with --verbose, it prints "no modprobe". It doesn't say if it's an error, or a warning, or what.
I think this message should be a little more clear.

$ sudo ubuntu-device-flash --verbose core rolling --channel edge --developer-mode -o ubuntu-snappy-rolling-edge-amd64-generic.img
