Hao,

I found your question interesting so I poked around some.  It looks like 
Anaconda uses pump and not a dhcpclient.  I cannot tell, if pump would 
allow you to retrieve a UUID. isys.py makes a call to isys.c via 
pumpnetdevice.  You would want to look at /usr/include/pump.h for the 
struct pumpNetIntf definition.  Files net.c and isys.c work with the 
information returned from pump.  At this late hour it all looks 
automagically to me.  I believe you will have to customize Anaconda to 
obtain your desired functionality.  It looks like only part of the dhcp 
information is used in Anaconda.  There are a couple of items for S390 
in pumpNetIntf.  I don't know if that is the same as xSeries.

Have fun.
