I'm not exactly sure what you're trying to do with this.  Or even why 
you need it.  With DHCP, once you get an IP address, you'll also get a 
default gateway.  All that does is tell your system if the system 
doesn't know where a packet goes, to shove it to the default.  I've 
NEVER needed to do this with DHCP, as it will provide basic networking 
functionality when you request the IP address.  Otherwise, what would be 
the point of DHCP?

Any dhcp client will set this up for you (or it should) and NM will 
definitely do so.  I'm just curious as to WHY you need to use a script 
for something that DHCP was designed to handle in the first place.

Have you tried to NOT run that script and see what happens?  I mean I 
would expect a script like this to be needed, maybe in '91 or '92.  Maybe.

Can you explain why this is needed?
