I would request we not put in symlinks.  The problem is that they are 
difficult to override.  Loading a later cpio has the effect of 
(attempting to) write over the current target of the symlink.  There is 
no "remove existing file or directory" entry in cpio.  This and the 
fact that initramfs only extends files are the two biggest limitations 
I've run into during the past 3 plus years.

We would be better off with a #! script instead, although that means 
the target has to accept at least the file name.
