Re: resolv.conf keeps old configurations
Automatically updating resolv.conf will work on Ubuntu 12.04 only in case resolv.conf itself is located in the folder /run/resolvconf. The folder /etc has got to hold a symbolic link to /run/resolvconf/resolv.conf.
karl@ubuntu12 /etc $ ls -l resolv.conf
lrwxrwxrwx 1 root root 27 Aug 5 13:43 resolv.conf -> /run/resolvconf/resolv.conf
karl@ubuntu12 /etc $
