cannot set initiator name during install

during install to a iscsi drive the installer (using netbootet 14.04 BETA) choose a random
initiatorname in the form

iqn.1993-08.org.debian:01:afadfcc960dd
or
iqn.1993-08.org.debian:01:1a9a2ac41d44

if the target in use ist based on the LIO target than there is no option to allow
every initator for the target :-(

so you must start installation. look at the server logfile for the initiatorname,
add it via targetcli and try again to log into the target; very annoying :-(

i have tried to edit the local initiatorfile (during another terminal)
but that changed the initatorname any more.

solution(s):
1)
the installer asks for target-ip, username, password, ...
and it optionaly asks for reverse-username und reverse password

just add a OPTIONAL question for the initatorname (maybe the first question)
if user presses just enter (like by username, ..) it chooses a default random
name like before

2) read the initatorname via DHCP, option 203. or via IBFT
