I trying to get known better about preseed features. So far, I haven't found answers to my needs, as follows: how to specify to tasksel installation of some packages like postfix, clamav etc. ? how to specify an action like "tar -xpjvf /cdrom/myfile.tar.bz2" or any other script I want to run in stage 3? Is there anywhere list of commands/options available? Regards.
