Functions

func FormatMountLabel

func FormatMountLabel(src, mountLabel string) string

FormatMountLabel returns a string to be used by the mount command. The format of this string will be used to alter the labeling of the mountpoint. The string returned is suitable to be used as the options field of the mount command. If you need to have additional mount point options, you can pass them in as the first parameter. Second parameter is the label that you wish to apply to all content in the mount point.
