sysMountPoint :: FilePathSource
FIXME: We should really get this value from the mount table.
ofNode :: FilePath -> IO (Maybe SpecialDevice)Source
Return the device represented by a device node, such as /dev/sda2. Returns Nothing if there is an exception trying to stat the node, or if the node turns out not to be a special device.
