Bug#586360: netcfg/get_hostname

[Nye Liu <nyet@nyet.org>]

With DCHP ENABLED:

I have tried:

Null string:
d-i netcfg/hostname string 
d-i netcfg/get_hostname string 

Seen false:
d-i netcfg/hostname seen false
d-i netcfg/get_hostname seen false

The only workaround seems to be to remove priority=critical from the kernel
command line (annoying, since there is no easy way to automate this short
of making your own iso or editing grub.cfg in your tftp netboot server)

There is an annoying side effect to this though; d-i netcfg/get_domain
is ignored, and the user always has to enter the domain.
