Bug Description

Binary package hint: usb-creator

usb-creator shows ridiculously large times when it records an image. Up to 220 minutes or so. I assume my USB 2.0 is not so slow...

I confirm that time calculation is inaccurate relative to the actual amount of time it takes to make the bootable disk. As well, the time is not sequential (that is to say the estimated time varies and goes faster/slower). This should be abstracted for the user and the time should be properly pre-calculated.

I particularly reacted to it going up to 17% fairly quickly and then staying there until done (then starting over with a different task -- installing the boot loader, creating the persistence area -- and a different idea of percentage and expected time).
