Syslinux - Dec 2008 - extlinux: usb for multiples machines

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.

Regards,

Change it to:
APPEND ro root=LABEL=myudisk initrd=../initrd

And then do this to the partition:
e2label /dev/sda1 myudisk

The solution is to mount the filesystem by UUID or LABEL instead of by
device name.  Most (although not all) distribution initrds support this
out of the box.

The initrd can also do custom searching, but that depends on the initrd.
