Ok. Consider that the chroot target directory is mounted ant 
/mnt/target/, and /mnt/config/ is a directory contianig configuration 
files, among others config file, and chroot-scrips/ directory.
Now, let's invoke grml-debootstrap with -d flag, e.g. grml-debootstrap 
-d /mnt/config. Now, my root directory (/) is /mnt/target/ actually, so 
/mnt/config/ is unreachable, but nevertheless /mnt/config/chroot-scripts 
are still going to be invoked, right? However, I should not reference 
any file from /mnt/config in them, as anything there is unreachable. 
Therefore, (for example) to compile some source code I should copy 
relevant files from /mnt/config/ to /mnt/target/ in advance? Perhaps 
this could be done with pre-scripts? Did I get this right? It's not like 
/mnt/config passed with the -d flag is mounted (or copied) to 
/etc/debootstrap where the default configuration residues.

Yes, it helps. Thanks.
In addition, I would ask is there a common way to log the output/error 
of the (grml-)debootstrap procedure, to see at which stage exactly a 
warning or an error occurred?
