No, bad idea. Let's say you want to install grml again (on another
disk/device) but don't want to remove for example apache this time.
Won't work if it's already deleted in the running system itself. The
only chance to restore the original state is to reboot. :-/

If you think you don't need the packages "foo, bar, blubs, blah"
then just run 'apt-get remove foo bar blubs blah' - but it's on your
own risk. Running it in the harddisk system is more safe.

Modifying the live-iso needs more "power" than accessing files in
the chroot installed on harddisk. Removing files on a (basically)
read-only medium where a overlay system manages read-write-tasks
requires ressources.

The "bad error/warning messages" derives from debian package
management and not from grml2hd! It does not matter whether you run
this *before* starting grml2hd, *within* grml2hd or afterwards.
