However allowing chgrp without editing /adm/users will solve different problem. Suppose bob is a teacher and he is teaching something to alice and carol. Alice want to show her files to only bob, and carol also want to show her files only to bob. How to do that ? Creating new group does not answer the purpose. The only solution of current Plan 9 is chgrp bob ... by host owner. My question comes from real problem. bob is a service program. alice and carol are system users.
