I can't tell you what Mandriva wants you to do; hopefully someone who  
uses it can actually answer your question. But I feel your pain --  
it's not that hard to maintain resolv.conf manually, and it's  
sometimes quite difficult to make the distro stop overwriting any  
manual configuration you try to do.

Which is why I gave up and wrote my own networking and DHCP-client  
scripts. They're nothing fancy, but you're welcome to them if they'd  
help you:

Simple bridging/bonding/network start/stop script and sample config  
files:

	http://zinux.cynicbytrade.com/svn/release/2.12/etc/files/bondcfg
	http://zinux.cynicbytrade.com/svn/release/2.12/etc/files/bridgecfg
	http://zinux.cynicbytrade.com/svn/release/2.12/etc/files/ifcfg

DHCP script with alternate resolv.conf location and IPv4 iproute2  
support:
