That will work, although if any other -awakeFromNib method (of an 
object in that nib) wants to use a relative path, you have a race 
condition, because the order in which -awakeFromNib methods are called 
is, basically, random.

But it's better to just avoid using relative paths, if possible. If 
you're accessing a file inside your bundle, you should use the 
NSBundle resource APIs to get its location.
