[syslinux] extlinux: usb for multiples machines

[Eriberto]

Hi!

I installed Debian in a pendrive and I used extlinux. I need a boot
for multiples machines. When I use the config file below, my pendrive
works fine:

DEFAULT linux
LABEL linux
KERNEL ../vmlinuz
APPEND ro root=/dev/sda1 initrd=../initrd

But I need a boot for any machine. Then, I tried it:

APPEND ro initrd=../initrd

but the boot stops after discover the correct location of the root
filesystem (/dev/sdc1 etc...).

What is the solution?

Thanks in advance.
