Functions

func EnsureDirAndMaxPerms

func EnsureDirAndMaxPerms(path string, perms os.FileMode) error

EnsureDirAndMaxPerms ensures that the given path exists, that it's a directory, and that it has permissions that are no more permissive than the given ones.

- If the path does not exist, it is created - If the path exists, but is not a directory, an error is returned - If the path exists, and is a directory, but has the wrong perms, it is chmod'ed
