Creating floppy images

Recently, I’ve needed to create DOS floppy images to use with VMWare. Floppy images end up being more convenient than trying to set up LANMAN or other networking in DOS. I used to use dd(1), but it’s come to my attention that the mkfs.vfat(8) now has a -C option, that does some of that hard work for you.

mkfs.vfat -C "myfloppy.img" 1440
mount -o loop -t vfat ./myfloppy.img /mnt

Near as I can tell, these images work great with DOS 6.2. I’m not quite sure on earlier versions.
