Specifying hostname as kernel boot parameter preseed file

[john doe <johndoe65534@mail.com>]

Hi,

I'm trying to comprehend in which conditions the hostname and domain can
be specified as kernel boot parameter:
As far as I understand it there are three ways to specify a hostname/domain:
- Kernel boot parameter (boot: hostname=<HOSTNAME>)
- By DHCP
- Static hostname in a preseed file ('d-i netcfg/hostname string <HOSTNAME)


I use a common preseed file for the debian installer with the exception
of the hostname that needs to be changed for eatch hosts.
So for example I would do something like:

boot: auto interface=auto url=<URL> hostname=try

On the installed system the hostname is always sed to 'bad'.

I would expect that 'hostname' in the above command would take
precedence over other hostnames that are specified by other means (DHCP
...).

What am I missing?


In other words: what is the best way to specify a hostname as kernel
boot parameter.
