installer: preseeding based on hostname

[Josef Wolf]

Hello!

I'm trying to build an install-CD with different configurations based on
the hostname.  I took the example from

  http://d-i.alioth.debian.org/manual/en.i386/apbs05.html#preseed-chainload

This is what the example suggests:

  d-i preseed/include_command \
        string if [ "`hostname`" = bob ]; then echo bob.cfg; fi

But unfortunately, there is a problem here: AFAICS, the include_command
is run immediately when the main preseed file is read.  At this early
stage the hostname is not set.  Therefore bob.cfg will never be read.

Is this a real bug or am I trying to do something very stupid?  Any ideas
how I can include different preseed files based on hostname?


BTW: The actual example is:

       d-i preseed/include_command \
            string echo if [ "`hostname`" = bob ]; then echo bob.cfg; fi

     which is obviously wrong (note the echo)
