add question (userinput) for hostname

[crazydave1981]

Dear Team,

Any way to get an userinput within a unnatended installation for setting the hostname?
Also looks like the terminal is broken after install, cant start it.

my .seed file looks like this.

Partitioning

ubiquity partman-auto/disk string /dev/sda
ubiquity partman-auto/method string regular
ubiquity partman-lvm/device_remove_lvm boolean true
ubiquity partman-md/device_remove_md boolean true
ubiquity partman-auto/choose_recipe select atomic

This makes partman automatically partition without confirmation

d-i partman/confirm_nooverwrite boolean true
