Comment 9 for bug 390504

In current karmic I'm getting these warnings pop up every minute or so, for a few read-only NFS filesystems. As Steve said, it is useless to provide warnings for filesystems to which the user cannot write (nor indeed can anyone else on the system, in this case). And I'm not sure why they're popping up unreasonably frequently... if you need more info to debug this, let me know.
