Just a small point here (and almost off-topic)... the /sbin/ip utility can often (usually) be a far more useful (and powerful) tool for doing things like that. It would be very easy to grep and then sed hardware addresses from the output of "/sbin/ip n". The /sbin/ip utility replaces (and obseletes) /sbin/route /sbin/arp and /sbin/ifconfig (and gives access to a huge amount of other networking functionality within the kernel, such as policy routing). It would require some cleaver server-side magic (eg, using php) to generate or supply kickstart config files based on client hardware addresses (certainly not impossible to do:) But in the end, wouldn't it be much easier to have a dhcpd server allocate static IPs based on the HW address, then have the host-specific ks.cfg file available based on IP rather than HW addresses?
