Some remarks on the way to success:

I think "APPEND" should be in an extra line. At least it is so in the
examples which i saw up to now.

"APPEND" is SYSLINUX/ISOLINUX speech, not GRUB.
I assume that this "APPEND" is handed over to the Linux kernel as
argument, like the others.

Interesting question, again.

I really wonder what the kernel thinks when seeing this "APPEND", of which
i still think is not appropriate.
I'd try in any case whether it can be omitted. If this remains as
successful end of this thread, then i fear that future readers might get
confused by it.


Have a nice day :)
