hi
how do we get /home on an other partition at installation time?
month ago i did it once by 'mistake', but yesterday when doing an install  
on an other machine, i just did not got it again!
i do remember something like 'Desktop Installation Modus' and then the  
automatic partitioning brought up /home on a second partition.
this would be great if someone can explain this in detail, how to get  
there.
thank you,
René
