func CopyMtimes

func CopyMtimes(source, dest *filesystem.FileSystem)

CopyMtimes will copy modification times for files from the source to the destination if the file data and metadata (other than mtime) are identical. Directory entry inode pointers are invalidated by this operation, so this should be followed by a call to dest.RebuildInodePointers().

func DeletedFilteredFiles

func DeletedFilteredFiles(rootDir string, filt *filter.Filter) error

func GetUnsupportedExt4fsOptions

func GetUnsupportedExt4fsOptions(fs *filesystem.FileSystem,
	objectsGetter objectserver.ObjectsGetter) ([]string, error)

func MakeBootable

func MakeBootable(fs *filesystem.FileSystem,
	deviceName, rootLabel, rootDir, kernelOptions string,
	doChroot bool, logger log.DebugLogger) error

func MakeExt4fs

func MakeExt4fs(deviceName, label string, unsupportedOptions []string,
	bytesPerInode uint64, logger log.Logger) error

func MakeKernelOptions

func MakeKernelOptions(rootDevice, extraOptions string) string

func ReplaceComputedFiles

func ReplaceComputedFiles(fs *filesystem.FileSystem,
	computedFilesData *ComputedFilesData,
	objectsGetter objectserver.ObjectsGetter) (
	objectserver.ObjectsGetter, error)

func SpliceComputedFiles

func SpliceComputedFiles(fs *filesystem.FileSystem,
	computedFileList []ComputedFile) error

func Unpack

func Unpack(fs *filesystem.FileSystem, objectsGetter objectserver.ObjectsGetter,
