[syslinux] is substitution possible?

[Wagner Ferenc]

Hi,

I'd like to write something like

append root=${NAME}-root

into PXELINUX's config file, that is, substitute the booting host's
DHCP name into the kernel command line.  Since that would be the only
varying part in the boot config of a bunch of machines, I'd rather not
use separate config files for each.  Is there a way to somehow achive
somehing like this?
