IMHO, it would be better to provide a /etc/dhclient-enter-hooks
while you are net installing the station, then remove it when
finished.
the dhclient-enter-hooks would be almost what you are doing :
#!/bin/sh
if [ x$reason = xPREINIT ]; then
case `ifconfig $interface` in
*flags=*[\<,]UP[\>,]*) exit 0 ;;
esac
