Functions ¶

func GetRSDP ¶

func GetRSDP() (string, error)

func GoBin ¶

func GoBin() string

func UrootPath ¶

func UrootPath(n ...string) string

UrootPath returns the full path for a uroot file with the UROOT_ROOT environment variable taken into account. It returns a proper value if UROOT_ROOT is not set. u-root was built to assume everything is rooted at /, and in most cases that is still true. But in hosted mode, e.g. on developer mode chromebooks, it's far better if u-root can be rooted in /usr/local, so successive kernel/root file system upgrades do not wipe it out.
