Dhcpcd has an option for that, i believe it's -R.  for example, on this
diskless router the dhcpcd on eth1 can't rewrite resolv.conf or the
netboot will fail: 
>>>FROM conf.d/net:
|  config_eth1=("dhcp")
|  dhcpcd_eth1=("-R")


However, you may need to find some way to get that information filled
out with your corporate intranet info before you use the vpn.
