On the TS7550, you must use nandctl to rewrite the initrd back to Flash, if you 
have made a change to boot sequence.

The supplied linuxrc runs a shell and waits until that shell is closed before 
doing the full Debian boot.

If you replace the linuxrc with one that doesn't wait, ie you want a 
non-interactive boot, how can you ever get back and alter the linuxrc?

There is no nandctl in the Debian image and the one in the initrd is linked 
against uClibc, so it won't run in the Debian environment.

There is no compiled nandctl in ts-7500-linux/binaries/ts-utils and no source 
in ts-7500-linux/sources.

What's a boy to do?

This is a similar situation to getting to a single-user boot on a more 
traditional large Unix-type system.  With the old RedBoot, there were ways to 
alter the boot sequence, but I can't see how to do that with the new Cavium 
systems.
