Hi,
my dhclient 4.3.1 on latest raspbian aquires leases on all interfaces
called for wlan0
dhclient -v -pf /run/dhclient.wlan0.pid -lf
/var/lib/dhcp/dhclient.wlan0.leases wlan0

The Problem is both leases eth0/wlan0 are written to lease file and on
ifdown wlan0 eth0 lease is also canceled,
so eth0 is also not working after, bound to ip also is the eth0 one
wlan0 is .39 .
I wrote a wrapper script for dhclient removing leases for other
interfaces from lease file to get it working for now:
cat /usr/local/sbin/dhclient
#!/bin/bash
echo dhclient $@ 2>&1 | tee -a /home/pi/dhc.log
echo $2 $6 $7 | tee -a /home/pi/dhc.log
if [ "$2" = "-r" ]; then
sed -r 's/^lease
[{]$/\0/;tp;d;:p;N;s/interface/\0/;Tp;s/'"$7"'/\0/;tm;d;:m;N;s/[}]/\0/;Tm'
"$6" > "$6"
cat "$6" >> /home/pi/dhc.log
fi
/sbin/dhclient "$@" 2>&1 | tee -a /home/pi/dhc.log
