Does anyone have any strong views about whether one should use FAT32 or ext[23] for the base filesystem for a bootable USB stick?
I was using FAT32, but it occurs to me that creating the USB sticks is much quicker if it's ext2 because it supports sparse files and so the overlay and persistent home don't need to be completely overwritten with zeros. Creation time is now 5m rather than 15m.
Are there downsides (other than it not being readable in Windows, which I don't care about)?
Looks like I'm not allowed ext4, because the livecd-iso-to-disk script complains! (That's presumably a bug, since ext4 ought to work fine.) Are there reasons to go for ext3 rather than ext2? I'm not quite sure what the journalling achieves--the number and size of the files on the partition isn't going to change, but obviously the data inside the overlay and persistent home will change.
