## Notes

### [tyhicks](https://launchpad.net/~tyhicks)

14.04 and 12.04 are not affected since ntfs-3g is not installed
setuid-root. While there is some debconf support for setting ntfs-3g as
setuid-root in the packaging, libfuse refuses to cooperate when it
detects that it is running in a setuid environment.
