// A floppy can be made available for your build. This is most useful for
// unattended Windows installs, which look for an Autounattend.xml file on
// removable media. By default, no floppy will be attached. All files listed in
// this setting get placed into the root directory of the floppy and the floppy
// is attached as the first floppy device. The summary size of the listed files
// must not exceed 1.44 MB. The supported ways to move large files into the OS
// are using `http_directory` or [the file
// provisioner](https://www.packer.io/docs/provisioners/file.html).
type FloppyConfig struct {
// A list of files to place onto a floppy disk that is attached when the VM
// is booted. Currently, no support exists for creating sub-directories on
// the floppy. Wildcard characters (\*, ?, and \[\]) are allowed. Directory
// names are also allowed, which will add all the files found in the
// directory to the floppy.
FloppyFiles []string `mapstructure:"floppy_files"`
// A list of directories to place onto the floppy disk recursively. This is
// similar to the `floppy_files` option except that the directory structure
// is preserved. This is useful for when your floppy disk includes drivers
// or if you just want to organize it's contents as a hierarchy. Wildcard
// characters (\*, ?, and \[\]) are allowed. The maximum summary size of
// all files in the listed directories are the same as in `floppy_files`.
FloppyDirectories []string `mapstructure:"floppy_dirs"`
FloppyLabel string `mapstructure:"floppy_label"`
