"USB Startup Disk" App incorrectly requires 4.4GB when using CD iso burned to DVD media.

[Robbie Williamson]

Binary package hint: usb-creator

Recreate steps:
1) Burn an Intrepid (8.10) Live CD image to DVD media (NOT CD media)
2) Boot into the Live image
3) Insert a 4GB (or less) USB stick
3) Select 'System' -> 'Administration' -> 'Create a USB startup disk'

The application correctly shows /cdrom with a size of 4.4GB, but incorrectly assumes that the DVD is full, thus requiring a USB stick of same or greater size.

The current code uses statvfs to determine the size of the mounted partition, rather than using the size of the partition itself. I've also just tested this with a DVD.
