VBox/NAT dhcp server and Lucid's resolvconf.

[Vasily Levchenko]

Greetings folks,

Recently VBox's community found that Lucid's guest resolvconf doesn't respect configuration sent by DHCP server (resolv.conf contains only auto-generated message), I've enabled debug script to dump variables on dhclient-enter-hooks.d and get following:

vbox at vbox-laptop:~$ less /tmp/dhclient-script.debug 
Thu Feb 25 13:39:12 MSK 2010: entering dhclient-enter-hooks.d, dumping variables.

vbox at vbox-laptop:~$ less /etc/resolv.conf 
# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
#     DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN

What could be recommendation about further debugging and does it like server bug (if yes what is wrong) or it's looks like a bug on resolvconf side? Previous ubuntu releases haven't demonstrated such behavior. 

Kind Regards,
Vasily.
