Unix != Windows ... UNIX does not have silly Windows file locking issues, so, as another put it, you copy, then update the kernel interfaces to point to new kernel, finally dump the old. You then do that every 10/15 minutes ... note, the size of the beast is ~1Mb, you can compile your own to make it smaller ... you could move it every minute without noticeable lag ...
