Requires that the target already be mounted

[Avi Greenbury]

When installing to a non-mounted device, unetbootin requires it be mounted and then try again.

Unetbootin requires root privileges to run, which are enough for it to be able to mount the device itself

Steps to replicate:
1. Plug drive in
2. Check it's unmounted
3. Ask unetbootin to write to it
4. unetbootin errors, asking you to make sure the drive is mounted

Expected behaviour

1. Plug drive in
2. Check it's unmounted
3. Ask unetbootin to write to it
4. unetbootin mounts the device and writes to it

Yeah, why wouldn't Unetbootin handle mounting itself?
