Code review comment for lp:~nuclearbob/utah/desktop-resolvconf

I've tested the code and it works fine. Anyway, I've got a couple of questions:

Could the `/etc/resolv.conf` file in the host machine be broken in some way
that it's unusable in the guest machine?

Should we remove the lines that append `apt-get install` commands to
`/etc/rc.local`?
