grml2usb: No space left on device is confusing #93
Description
Just tried to install a Grml ISO to my USB device for booting and received:

I was confused:
❯ df -h /tmp

/dev/mapper/vg0--tranquility-rootfs 20G 17G 2,1G 89% /
It turned out that the destination device was the problem

Maybe we can check the free space before trying to write and warn the user?
