Description of problem: When the parameter of --overlay-size-mb is incorrect (e.g. 256MB instead of 256) the script doesn't stop but an arbitrary (large?) overlay size is used and the filesystem on USB stick (vfat) is garbled. Version-Release number of selected component (if applicable): livecd-tools-017.1-1.fc9.i386 How reproducible: I tried only once, but it should be deterministic. Steps to Reproduce: 1. connect a vfat USB stick 2. run livecd-iso-to-disk --overlay-size-mb 256MB /tmp/F10-Beta-i686-Live-KDE.iso /dev/sdb1 Actual results: The script prints the message that the argument is incorrect, but continues anyway. After some time it stops with "cannot write some file" sort of message, the filesystem on the USB stick is garbled Expected results: The script should stop with the message that the argument is incorrect.
Fixed in git; thanks for the report
