lmn-prepare asks twice for hostname

[michaelkohls]

the script asks twice for enter the hostname, but the intention of second input is the domain. I think the problem is in line 897. Should be
''domainname = inputdomainname(domainname_saved) if not unattended else domainname_saved''

Thank you for your contribution. Fixed also the writing of inputDomainname.
