[Bug 49917] Re: DNS server settings don't survive a reboot

[Luka Renko]

Your /etc/resolv.conf has this comment:
# 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

Do you have resolveconf package installed from universe?
http://packages.ubuntu.com/dapper/net/resolvconf

Can you try removing this package and see if it helps?
