Functions ¶

func BuildDir ¶

func BuildDir(importPath string) string

func BuildDirOrMigrate ¶

func BuildDirOrMigrate(importPath string) (string, error)

func DefaultTags ¶

func DefaultTags() []string

func Env ¶

func Env() []string

func InitDeps ¶

func InitDeps(initPkg string) []string

func PackageDir ¶

func PackageDir(pkg string) (string, error)

func PackageDirs ¶

func PackageDirs(pkgs []string) ([]string, error)

PackageDirs returns the package directories, in the same order as the argument

func PermSizeInKB ¶

func PermSizeInKB(devsize uint64) uint32

func TargetArch ¶

func TargetArch() string

Types ¶

type BuildEnv ¶

type BuildEnv struct {
	BuildDir func(string) (string, error)
}

func (*BuildEnv) Build ¶

func (be *BuildEnv) Build(bindir string, packages []string, packageBuildFlags, packageBuildTags map[string][]string, noBuildPackages []string) error

func (*BuildEnv) MainPackages ¶

func (be *BuildEnv) MainPackages(pkgs []string) ([]Pkg, error)

type Pack ¶

type Pack struct {
	Partuuid       uint32
	UsePartuuid    bool
	UseGPTPartuuid bool
	UseGPT         bool
	ExistingEEPROM struct {
		PieepromSHA256 string // pieeprom.sig
		VL805SHA256    string // vl805.sig
	}
}

Pack represents one pack process.

func NewPackForHost ¶

func NewPackForHost(hostname string) Pack

func (*Pack) GPTPARTUUID ¶

func (p *Pack) GPTPARTUUID(partition uint16) string

GPTPARTUUID derives a GPT partition GUID for the specified partition.

All gokrazy GPT partition GUIDs start with the same prefix and contain the hostname-derived hash + the partition number in the last block (“node identifier”).

func (*Pack) ModifyCmdlineRoot ¶

func (p *Pack) ModifyCmdlineRoot() bool

ModifyCmdlineRoot() returns true if the -kernel_pkgs cmdline.txt file needs any modifications. This will be true on most gokrazy installations.

func (*Pack) Partition ¶

func (p *Pack) Partition(o *os.File, devsize uint64) error

func (*Pack) PermUUID ¶

func (p *Pack) PermUUID() string

func (*Pack) RereadPartitions ¶

func (p *Pack) RereadPartitions(o *os.File) error

func (*Pack) Root ¶

func (p *Pack) Root() string

type Pkg ¶

type Pkg struct {
	Name       string `json:"Name"`
	ImportPath string `json:"ImportPath"`
	Target     string `json:"Target"`
}

func (*Pkg) Basename ¶

func (p *Pkg) Basename() string
