Created attachment 784934 [details] patch for livecd-iso-to-disk Description of problem: I'd say this is more an enhancement than a problem - livecd-iso-to-disk works as advertised. When writing to a FAT32 partition, --swap-size-mb, --overlay-size-mb and --home-size-mb are capped at 2 gigabytes, presumably because at one time somebody thought a file an a FAT32 partition couldn't be larger than 2 gigabytes (2^31-1 bytes). I've used files on FAT32 as large as 2^32-1 (4 GB) and they work on both Windows 8 and Linux. Moreover, 'liveusb-creator' actually will make a 4 GB persistent overlay. So I patched the livecd-iso-to-disk script to change to cap to 4095 MB and everything appears to work. I don't know what other testing / research is required before this can be changed, but I'm offering the attached patch. Version-Release number of selected component (if applicable): 19.5-1.fc19
