One thing I've noticed in a lot of recent distros is that users all have their own groups with the same name as their user name. What's the purpose of that? Groups are made to group users together in some ways, such as users, management, IT, etc. Seems pointless to have all these single-user groups. I seem to recall Unix systems before did have everyone's default group be users.
Why does every user have their own group?
