Overview

To avoid circular imports between db/mount/etc. packages, let's define the basic atomfs types in their own package that everyone will then import.

type Molecule

type Molecule struct {
	ID   int64
	Name string
	// Atoms is the list of atoms in this Molecule. The first element in
	// this list is the top most layer in the overlayfs.
	Atoms []Atom
	// contains filtered or unexported fields
}

func NewMolecule

func NewMolecule(config Config) Molecule

func (Molecule) Mount

func (m Molecule) Mount(dest string, writable bool) error

func (Molecule) MountUnderlyingAtoms

func (m Molecule) MountUnderlyingAtoms() error

MountUnderlyingAtoms mounts all the underlying atoms at config.MountedAtomsPath().

func (Molecule) OverlayArgs

func (m Molecule) OverlayArgs(dest string, writable bool) (string, error)

OverlayArgs returns all of the mount options to pass to the kernel to actually mount this molecule.
