The parameter to --with-initrd should be the name of the initrd to use;
"yes" or "no" are not valid parameters. I note that the help text is
misleading in this regard, it should probably be fixed up to say
something like "Specify an initrd to use". 

While it's unlikely that someone will have an initrd called "no", this
issue can only occur with incorrect usage of the bootwrapper configure
script. I'd happily accept a patch fixing up the help text, though.

Thanks,
Mark.
