[Grml] Fully automated grml2hd

[T]

Hi

Several suggestions regarding the grml2hd:

- I noticed that not all questions asked are in the config file. hostname
is one of the example. 

- How about able to configure default language and time zone? 

- It might be a good idea to allow user to specify their own config files,
but partition and mbr are still passed from the command line. So, eg,
the config file can be provided from floppy, the same setting (from
floppy) can be re-used over and over again. 

just my 2c

thanks
