Re: problems with resolv.conf - nameserver

This package causes problems with network-manager, which will not update
/etc/resolv.conf for example while dhcp if resolvconf is there.
IMO it's not a problem of devian-live itselves.
Do you need the package resolvconf in your live-system?
If you don't need it and it is not in your packageslist, set up
apt-recommends off (for example with "lh_config --apt-recommends
disabled" or in your build-configs), so it won't be installed, if a
package you use recommends (and not need!) it.
