Omit Standard System Packages
 

During the installer specifically in 'tasksel', I'm given a few options. I generally de-select every possible option but what exactly is under the package group name 'Standard System'?

Obviously when I de-select 'Standard System', basically my installation of 'netinst' is almost immediately completed and I'm asked to reboot. How can I see or find out what exactly am I omitting from the system?

Thank you. Very helpful.
