I recently switched from slackware to debian. Under slack, when users were added they were defaultly added to the group "users". I see debian gives each user his/her own group.
1. Why did debian adopt this method? 2. If say, I want to add two of my users to the same group, is it safe to add them to the already existing "users (GID=100)" group, or is this reserved for some program that comes with debian? Thanks.
