Bug#593811: debian-installer: DHCP requests restart Livebox modem/router

[Alain rpnpif <rpnpif@free.fr>]

Other tries :
I rebooted again the last mini.iso. On normal mode, udhcpc get normally an IP
from the Livebox.
Under busybox, the logs :
I run : udhcpc several times sequentially
udhcpc
Sending discover
Sensend select for 192.168.1.12 (the obtained IP)
Sending select for 192.168.1.12 (the obtained IP)
sending select for 192.168.1.12 (the obtained IP)
(Livebox reboot)
udhcpc has been called with an unknown param. leasefail

After that starting of Livebox is completed :
udhpc
udhcpc (v1.17.1) started
Sending discover...
Sending select for 192.168.1.12...
Lease of 192.168.1.12 obtained, lease time 604800
udhcpc
udhcpc (v1.17.1) started
Sending discover...

(Livebox reboot)
After restart completed
udhpc
udhcpc (v1.17.1) started
Sending discover...
Sending select for 192.168.1.12...
Lease of 192.168.1.12 obtained, lease time 604800
udhpc
udhcpc (v1.17.1) started
Sending discover...
Sending select for 192.168.1.12...
Lease of 192.168.1.12 obtained, lease time 604800
udhcpc
udhcpc (v1.17.1) started
Sending discover...

Sending discover...
(Livebox reboot)

So perhaps, Livebox reboots when udhcpc send requests too frequently 
(timeout too short ?).
The reboot of the Livebox occurs or not.
