perhaps its worth pointing out that 255 is a kernel limit - unless
Documentation/i386/boot.txt
is oo-date:
**** THE KERNEL COMMAND LINE
The kernel command line is a null-terminated string up to 255
characters long, plus the final null.
so any error msg from pxelinux is reflecting the fact that you wont
succeed anyway.
