hi there are two types of users/groups. system users and normal users. system
groups include groups like apache, mail, etc nd other app and system groups.
there are users like root who are members of more system groups as well. what is the use of these system groups? can i create a normal user as a member of one of these system groups? say
apache. if i can what additional functionality will that user get. will that user get full
access to all apache files? including changing the config etc? thnx in advance
