func CleanScopedPath ¶

func CleanScopedPath(path string) string

CleanScopedPath preappends a to combine with a mnt path.

func EnsureRemoveAll ¶

func EnsureRemoveAll(dir string) error

EnsureRemoveAll wraps `os.RemoveAll` to check for specific errors that can often be remedied. Only use `EnsureRemoveAll` if you really want to make every effort to remove a directory.

Because of the way `os.Remove` (and by extension `os.RemoveAll`) works, there can be a race between reading directory entries and then actually attempting to remove everything in the directory. These types of errors do not need to be returned since it's ok for the dir to be gone we can just retry the remove operation.

This should not return a `os.ErrNotExist` kind of error under any circumstances

func ResolveScopedPath ¶

func ResolveScopedPath(root, path string) (string, error)

ResolveScopedPath evaluates the given path scoped to the root. For example, if root=/a, and path=/b/c, then this function would return /a/b/c.
