[lug] Linux and ATT at Home

[Holshouser, David]

I'd say that uninstalling pump isn't necessary if you edit the config file
/etc/sysconfig/network-scripts/ifup
and replace the pump call with a call to dhcpcd
==================
    echo -n "Determining IP information for $DEVICE..."
    if /sbin/pump $PUMPARGS -i $DEVICE ; then
        echo " done."
    else
        echo " failed."
        exit 1
    fi
---------->>>>>>>>
    echo -n "Determining IP information for $DEVICE..."
    if /path/to/dhcpcd $PUMPARGS -i $DEVICE ; then
        echo " done."
    else
        echo " failed."
        exit 1
    fi
==================
and if you are willing to do this, then searching for, understanding, and
changing PUMPARGS shouldn't be too big a leap.
