Functions

func Align

func Align(count int, alignment int) int

Align returns count aligned to the next multiple of alignment, or count itself if it is already aligned.

Types

type Directory

type Directory struct {
	Node
	Mode int
}

type Disk

func GetBaseDisk

func GetBaseDisk() []Disk

func (Disk) CalculateImageSize

func (d Disk) CalculateImageSize() int64

CalculateImageSize determines the size of the disk, assuming the partitions are all aligned and completely fill the disk.
