This document explains how the BOINC Linux installer works.

Users and groups

The installer creates a user boinc and a group boinc.

All files created by the installer are owned by boinc, and all BOINC processes (the client and science applications) run under boinc. This provides a measure of protection, since these processes cannot access file or directories with no 'other' permissions set.
