Exactly therefor the script 'remove-packages-server' exists and is
integrated into grml2hd. The modularity allows to run
remove-packages-server even on the harddisk installation, absolutely
independent from grml2hd.

Using the existing, working package management is less complex and
easier to mantain than rewriting a 'cp -a /from /to' to exclude
specific files.

No, the copy-some would add complexity. If you don't believe me just
read the source.

As long as it does not fail it's not an error but a warning.
Warnings are kind of normal behaviour. They just let you know that
there *might* be something which *might* lead into problems ("I
expected foo but received bar"). As long as it does not fail -
therefor interrupts - it's not a problem at all. If you are not used
to see warnings, you either aren't used to Debian or your Distro
hides such stuff from you.
