} I'm sorry, this is easy to fix... have a set of tools you copy to /ibin
} that are used for the install (all staticly compiled binaries hopefully)
} and run the install world out of /ibin...  maybe include some binaries
} for system recovery to make sure...

... but as soon as you run the stuff in /ibin to install the new userland,
you won't even be able to run a shell script, because the newly installed
/bin/sh will be using the new signal syscalls.  The install process will
have to include installing a new kernel and will have to be followed by
an immediate reboot.
